Next, transmission and reception of mail via the Internet 4 will be described.

The mechanism for sending or receiving a mail via the Internet 4 is very similar to the mechanism for sending a mail such as a postcard. In the case of mail, Write a letter, 2. 2. Post to the post. 3. Transfer between post offices; One letter arrives at the recipient through the four steps of delivering to the mailbox.

In the case of mail via the Internet 4, 1. Write an email on the email sending and receiving program,
2. 2. Press the send button of the mail sending and receiving program.
3. Transfer between mail servers After going through the four steps of pressing the receive button of the mail sending and receiving program,
The email reaches the other party.

The mail sending / receiving program is a program for writing and sending mail to the other party or receiving the mail sent by the other party. The mail sending / receiving program is also called a mailer, and has a function corresponding to a post and a mailbox.

Most mail sending / receiving programs have an editor function for displaying mail on a screen or writing mail. The user operates the mail sending / receiving program to send or receive mail.

As a typical mail sending / receiving program,
Microsoft's OutlookExpress (TM), Qualcomm's Eudora Pro (TM), and free software Becky! InternetMail or Al-Mail32.

The mail server plays the role of a post office, so to speak. The mail server receives the mail sent by the mail sending / receiving program, and sends the mail to the mail sending / receiving program. As a typical mail server program,
There is sendmail (trademark) of Sendmail Corporation.

The mail server has three main roles. First, the mail received from the mail sending and receiving program,
Properly sending to other mail servers. Second
Is to organize and manage mails received from other mail servers by destination (user). Third, sending the managed mail to the mail sending / receiving program in response to a request from the mail sending / receiving program.

The procedure for the mail sending / receiving program to send the mail to the mail server is different from the procedure for the mail server to send the mail to the mail sending / receiving program, and the communication procedure is different.

The communication procedure is called a protocol. The processing by which the mail sending and receiving program sends mail to the mail server and the processing by which the mail server sends mail to the mail server include SMTP (Simple Mail Transcript).
sfer protocol) is widely used.

The processing for receiving the mail from the mail server by the mail sending / receiving program includes POP3 (Post Office).
Protocol Version 3) is widely used.

The port corresponding to SMTP and the port corresponding to POP3 in the mail server are different from each other. When sending mail, the mail sending and receiving program communicates with the mail server via the port corresponding to SMTP,
When receiving mail, it communicates with the mail server via the port corresponding to POP3.

In the case of mail, a letter sent from a foreign country is stamped for each country that has passed. Similarly, the mail is also marked with a postmark.

When a mail is transmitted, postmark information is sequentially added to the head of the mail text each time the mail passes through the mail server. Since attached to the head, this postmark information is called a header.

The header is roughly composed of three blocks. The block attached to the mail transmission / reception program is arranged in the lowermost part (the part close to the text), and the blocks attached to the mail server are arranged in the two upper parts.

The header stores new information at the top.

The header information attached to the mail sending / receiving program is composed of the same information as the address of the letter. From stores the mail address of the sender, To stores the mail address of the destination, and Subject stores the title.

Of the blocks attached by the mail server, Re
In ceived, a time stamp is stored. form stores the name of the mail server that passed.

The mail server sends this mail
Add Received block. Therefore, the mail server through which the mail has passed can be known by checking the description of the Received block in order from the bottom to the top.

Next, the setting of the mail sending / receiving program will be described. The information that must be set correctly in order to send mail is the e-mail address corresponding to the mail sending / receiving program and the host name of the mail server corresponding to SMTP.

The e-mail address corresponding to the mail transmission / reception program is a source address corresponding to the sender name. When the e-mail address corresponding to the e-mail transmission / reception program is not set, the person who received the e-mail cannot know the sender, and when the destination is unknown, the e-mail cannot be returned.

The mail sending / receiving program inserts an electronic mail address corresponding to the mail sending / receiving program into the From line in the header. The e-mail address corresponding to the mail transmission / reception program is also used as a destination when the other party writes a reply. Depending on the mail transmission / reception program, the destination of the reply can be changed by setting the item of the reply address.

The host name of the mail server to which the mail sending / receiving program sends mail is set as the host name of the mail server corresponding to SMTP. When sending a mail, the mail sending / receiving program sends the mail to the mail server based on the host name of the mail server corresponding to the SMTP. The host name is described as, for example, mailserver.so-net.ne.jp.

The electronic mail address and the host name are described based on the domain name. In the domain name, the country name, the type of organization, and the company name are represented by connecting “.”. In a domain name, a larger section is located later.

The e-mail address is the name of the user,
It is indicated by attaching "@" as a delimiter and further connecting a domain name.

The host name is described by adding "." As a delimiter to the server name and further connecting the domain name.

The e-mail address or host name is a unique e-mail address or host name as described above.

Upper and lower case letters are used for the domain name of the e-mail address and the host name, but these are not distinguished.

Next, transmission of a mail to the mail server by the mail transmission / reception program will be described. The mail sending / receiving program must obtain the IP address corresponding to the host name when sending mail. The IP address is described by a combination of a numeral and “.”, For example, 192.168.0.1.

The DNS is a system for converting a host name into an IP address. Internet 4 has several DNs
S server is installed. When a host name is sent to one of the DNS servers, the DNS server returns an IP address corresponding to the host name.

For example, the DNS server 6-1 in FIG. 1 records an IP address aaaa in association with the host name A.

The mail sending / receiving program sends the I / O of the mail server from the DNS server immediately before accessing the mail server.
Ask your P address.

Next, the procedure for sending a mail from the mail sending / receiving program to the mail server will be described. The mail sending / receiving program and the mail server send mail from the mail sending / receiving program to the mail server according to the SMTP procedure.

The procedure of SMTP is TCP (Transmission Control).
l Protocol) setup, calling the mail server, preparing for transmission, notification of destination, transmission of text, confirmation of termination,
And termination of TCP. The processing of calling the mail server, preparing for transmission, notifying the destination, transmitting the text, and confirming the end are all composed of a request from the mail transmission / reception program and a reply from the mail server.

In the SMTP processing, the mail transmission / reception program and the mail server communicate with each other using a command statement and a reply code. For example, the command statement “RCPT from:
y@so-net.ne.jp ", the RCPT is a command to notify the mail destination, and the mail destination is y@so-net.ne.jp.
jp.

In the reply code, for example, “Yes”
250. To explain some of the reply codes, 251
Indicates "No such user exists", 450
Indicates "Mailbox is in use" and 451 indicates "
452 indicates "Insufficient resources for processing" and 501
Indicates "The command syntax is incorrect."
Indicates "command not available" and 550 indicates "mailbox does not exist".

The mail has a broadcast function. The lifetime broadcast function is a function to send an e-mail with the same text to many people.

For example, if a plurality of mail addresses are described in the To line of the header, the mail sending / receiving program
The process of transmitting the PT command is repeated for each address described in the mail address.

The Cc (carbon copy) line or B
Broadcasting can also be performed using a special header such as a cc (blind carbon copy) line.

When a mail is transmitted using the Cc line or the Bcc line, the recipient of the mail knows that a copy of the mail has been received because his / her address is not described in the To line of the header. be able to.

When sending an e-mail using the Cc line,
The header stores the mail address of the other party.
When the mail is transmitted using the Bcc line, the mail transmitting / receiving program deletes the Bcc line from the header after transmitting the RCPT command, and transmits the text. Bcc
Sending an e-mail using a line is effective when you do not want to inform the other party of the broadcast destination.

Next, a process in which the mail server searches for a mail server near the destination and transfers the mail server will be described. The process of transferring mail from the mail server to the mail server,
It is executed according to the procedure of SMTP.

In the process of transferring mail from the mail server to the mail server, the mail server transmitting the mail cuts out the domain name from the mail destination and sends the cut out domain name to the DNS server.

Since the DNS server records the relationship between the domain name and the host name of the mail server as an MX record, it sends the host name of the mail server corresponding to the domain name to the mail server that sent the domain name. .

For example, the DNS server 6-2 in FIG. 1 records the host name B in association with the domain name BBB.

The mail server having received the host name sends the host name to the DNS server.

Since the DNS server records the relationship between the host name and the IP address as an A record, the DNS server transmits the IP address corresponding to the host name to the mail server that transmitted the host name.

For example, the DNS server 6-2 in FIG. 1 records the IP address bbbb in association with the host name B.

The mail server that has transmitted the IP address transmits the mail to the mail server corresponding to the domain name of the mail destination based on the above-described SMTP procedure.

The mail server can broadcast a mail using a mailing list. When broadcasting mail using a mailing list, the alias function is used.

A mail server using the alias function records a plurality of addresses in advance in groups corresponding to predetermined mail addresses (representative addresses). Upon receiving the mail addressed to the representative address, the mail server retransmits a copy of the mail to all of the plurality of addresses recorded corresponding to the representative address.
The mail server sends mails one after another to the registered mail addresses without rewriting the header.

The mail server corresponding to the domain name stores the received mail in a mailbox called a spool. The mail server manages the mail for each user, and distributes the mail when the receiving button of the mail sending / receiving program of the user corresponding to the destination is pressed.

The reason that the mail server does not send mail to the mail sending / receiving program based on SMTP may be because the device executing the mail sending / receiving program is not operating or is not connected to the Internet 4. It is.

The mail server sends mail to the mail sending / receiving program based on POP3. POP3 procedure is TC
Set up P, call mail server, authenticate user, check mailbox contents, check number of incoming calls,
The process consists of receiving the body text, requesting deletion, confirming termination, and terminating TCP. The process of calling the mail server, authenticating the user, checking the contents of the mailbox, checking the number of incoming calls, receiving the text, requesting deletion, and checking the end are all requests from the mail sending / receiving program and the reply from the mail server. It consists of.

The command text and reply code in POP3 are different from the command text and reply code in SMTP.

In POP3, mail reception processing is not executed unless the user is authenticated by a user ID and password registered in the mail server in advance.

FIG. 7 is a diagram for explaining a program executed by the PDA 1 for sending a mail. An operating system (hereinafter, referred to as an OS) 101 is a program that controls basic operations of the PDA 1.

The driver 102-1 is a program for controlling the display on the display unit 11. The driver 102-2 is
This is a program for controlling the operation of the touchpad control unit 38. The driver 102-3 is a program that controls the sound reproduction of the sound reproduction unit 42. Driver 102-4
Is a program for executing a process corresponding to the input of the jog dial 23.

[0130] The library 103 stores a plurality of processing routines used by application programs such as the mail transmission / reception program 104.

The mail transmission / reception program 104 includes the cradle 2-1 or 2-2, the personal computer 3
-1 or 3-2 and a program for sending or receiving a mail via the Internet 4.

The configuration of the program shown in FIG. 7 is the same as the configuration of a conventional program of a device for transmitting and receiving mail.

FIG. 8 is a diagram for explaining a program executed by the PDA 1 for transmitting a mail or receiving a mail. When receiving the mail from the mail server 5-2, the mail transmission / reception program 104 causes the display unit 11 to display, for example, an image shown in FIG. When displaying the received mail, the mail sending / receiving program 104 supplies the received mail to the interpreter 106.

The library 105 includes an interpreter 106
Contains the routines used when executing scripts.

The interpreter 106 is a program plugged into the mail transmission / reception program 104, extracts a script included in the mail, and executes the extracted script. For example, the interpreter 106
In response to the execution of the script, the driver 102-1
A predetermined image is displayed on the display unit 11, and the driver 102-
3 causes the sound reproduction unit 42 to reproduce a predetermined sound.

The interpreter 106 causes the drivers 102-1 to 102-4 corresponding to the display unit 11 or the audio reproduction unit 42 to execute display or audio reproduction, etc., so that the display unit may differ depending on the model of the PDA 1. Even if the audio playback unit 11 or the audio playback unit 42 is different, the display or the audio playback by the interpreter 106 is executed reliably and accurately.

The interpreter 106 is connected to the display 11
Alternatively, the driver 102-1 to 102-4 corresponding to the device such as the sound reproducing unit 42 executes processing such as display or sound reproduction, so that various devices operating according to the execution contents of the script are stored in the PDA 1. Even if incorporated, the control of the device by the interpreter 106 is executed reliably and accurately.

The mail transmission / reception program 104
When the script is included in the mail to be displayed, the interpreter 106 may be activated and the library 105 may be loaded.

FIG. 10 is a diagram for explaining the structure of the interpreter 106 in more detail. The interpreter 106 includes a parsing module 121, an execution module 122, and an output module 123.

For example, as shown in FIG. 11, when the mail transmission / reception program 104 attempts to display the mail 151, the syntax analysis module 121 receives the mail 151 from the mail transmission / reception program 104 and includes the mail 151 in the received mail 151. The extracted script is extracted and supplied to the execution module 122.

FIG. 12 is a diagram showing an example of the structure of a mail 151 transmitted or received by the PDA 1. When the script is stored in the mail 151, the script is stored after the mail body. When the stored script requires data, the mail 151 stores data necessary for execution of the script by the interpreter 106 following the script.

The syntax analysis module 121 sends the mail 15
When data is stored together with the script in 1, the data is extracted together with the script, and the extracted data is supplied to the execution module 122 together with the script.

FIG. 13 is a view for explaining the flow of processing of the interpreter 106 when the mail 151 stores a script. When the script is extracted from the mail 151, the syntax analysis module 121 supplies the extracted script to the execution module 122.

The execution module 122 that has received the supply of the script executes the script. Output module 12
3 displays an image, outputs a sound, or outputs data 171 in accordance with the result of executing the script.
Is stored in the EDO DRAM 34, for example.

On the other hand, when the syntax analysis module 121 does not extract the script from the mail 151 (when the script is not included in the mail 151), as shown in FIG. Is executed by the mail transmission / reception program 104, and normal mail processing is executed. At this time, the mail transmission / reception program 104 supplies text data 191 corresponding to the body of the mail 151 to the driver 102-1. The driver 102-1 causes the display unit 11 to display the body of the mail 151 based on the text data 191.

FIG. 15 shows a mail 151 for executing Othello.
It is a figure showing the example of. In the example shown in FIG. 15, the mail 151 is composed of a text and a script. The script included in the mail 151 shown in FIG. 15 is a MIME (Multi Purpose Internet Mail Extension)

In the mail 151 shown in FIG.
O: "Someone"<someone@sony.co.jp>"~" Othello 2
It is a hand. "" Corresponds to the text, "------ = _ NextPart_000_0
011_01BFA9E7.2EE28580 "to" ---- Next_Part (Wed_Apr_1
9_11: 42: 48_2000_705) ---- "corresponds to the script.

FIG. 16 is a diagram schematically showing execution of a script. Execution of a script is classified into an input unit and an execution unit.

At the input unit, the syntax analysis module 1
With 21, a script is extracted from the mail 151.

The execution section further comprises a data input section, a processing execution section, and an output section. In the data input unit, the execution module 122 includes, for example, the driver 1
At 02-1, an input image is displayed on the display unit 11, and the driver 102-2 controls the input from the touch pad control unit 38.

The input in the data input unit is performed by the execution module 122 by, for example, the tablet, key 22, jog dial 23, sensor, memory stick interface 35, external keyboard, modem, USB interface 36, infrared communication unit 40, or drive 5.
This is executed by controlling the driver corresponding to the second or the like.

In the processing execution section, the execution module 12
2 executes the processing logic of the script.

In the output section, the output module 123
Corresponds to the processing in the processing execution unit, for example, causes the driver 102-1 to display the image of the processing result on the display unit 11, and causes the driver 102-3 to output the sound of the processing result to the sound reproduction unit 42. Output.

The output from the output unit is output from the output module 123 to, for example, the display unit 11, the modem, and the audio reproduction unit 4.

As shown in FIG. 19, when the user inputs a new hand, the execution module 122 executes ontap ().
The method gets the coordinates on the Othello board where the new hand was entered. The execution module 12 determines, using the check () method, whether or not the coordinates corresponding to the new hand satisfies the requirements specified in the Othello rule, and determines that the coordinates do not satisfy the requirements specified in the Othello rule. If so, an error is notified by the confirm () method (an error message is displayed on the display unit 11), and the execution of the ontap () method is repeated.

If it is determined that the new hand satisfies the requirements specified in Othello's rules, the execution module 1
In step 22, the face of the frame is updated by the update () method, as shown in the example of FIG. Output module 123
Executes a process of sending an e-mail to the other party by the sendmail () method, as shown in an example in FIG.
Processing ends with the t () method.

Next, mail transmission processing by the PDA 1 executing the mail transmission / reception program 104 will be described with reference to the flowchart of FIG. In step S11, the mail sending / receiving program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-1 to the DNS server 6-1 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-1 is obtained from the server 6-1.

The processing of steps S12 to S18 is executed based on, for example, the SMTP procedure.

In step S12, the mail transmission / reception program 104 causes the USB interface 36 to connect to the mail server 5-1 by specifying an IP address via the cradle 2, the personal computer 3, and the Internet 4. In step S13, the mail sending / receiving program 104
6 calls the mail server 5-1 via the cradle 2, the personal computer 3, and the Internet 4 (calls a mail server program (for example, sendmail (trademark) or the like) executed by the mail server 5-1).

In step S14, the mail sending / receiving program 104 causes the USB interface 36 to prepare the mail server 5-1 for sending mail (procedure for sending mail to the mail server program executed by the mail server 5-1). Will be notified). In step S15, the mail sending / receiving program 104
Notifies the USB interface 36 of the destination (mail address) of the mail to be transmitted to the mail server 5-1.

In step S16, the mail sending / receiving program 104 causes the USB interface 36 to send mail to the mail server 5-1. Step S17
, The mail transmission / reception program 104 causes the USB interface 36 to confirm completion of processing with the mail server 5-1.

In step S17, the mail transmission / reception program 104 causes the USB interface 36 to disconnect from the mail server 5-1 and the process ends.

As described above, the PDA 1 communicates with the mail server 5-
1 can send an email.

The process by which the mail server 5-1 transfers the mail to the mail server 5-2 is the same as the mail transmission process except for the process of acquiring the host name corresponding to the mail destination. Is omitted.

Next, with reference to the flowchart of FIG. 23, a description will be given of a mail reception process by the PDA 1 executing the mail transmission / reception program 104. In step S31, the mail transmission / reception program 104 causes the USB interface 36 to transmit the host name corresponding to the mail server 5-2 to the DNS server 6-2 via the cradle 2, the personal computer 3, and the Internet 4, An IP address corresponding to the mail server 5-2 is obtained from the server 6-2.

The processing of steps S32 to S40 is executed based on, for example, the procedure of POP3.

In step S32, the mail sending / receiving program 104 causes the USB interface 36 to specify the IP address via the cradle 2, the personal computer 3, and the Internet 4 to connect to the mail server 5-2. In step S33, the mail transmission / reception program 104
6 calls the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4.

In step S34, the mail sending / receiving program 104 sends the PDA 1 to the USB interface 36.
The user ID and the password of the user are transmitted to the mail server 5-2 via the cradle 2, the personal computer 3, and the Internet 4, and the mail server 5-2 executes the user authentication process.

In step S35, the mail transmission / reception program 104 causes the mail interface 5-2 to check the contents of the mail box (where the mail addressed to the user of the PDA 1 is stored) in the USB interface 36.

In step S36, the mail transmission / reception program 104 sends the PDA 1 to the USB interface 36.
The number of incoming e-mails to the user is transmitted to the mail server 5-2, and the number of incoming e-mails is received.

In step S37, the mail transmission / reception program 104 causes the USB interface 36 to transmit the mail addressed to the user of the PDA 1 to the mail server 5-2, and to receive the transmitted mail. In step S38, the mail transmission / reception program 104 causes the USB interface 36 to request the mail server 5-2 to delete the mail addressed to the user of the PDA 1. Mail server 5-2
Deletes the email addressed to the user of PDA1.

In step S39, the mail transmission / reception program 104 causes the USB interface 36 to confirm the end of the processing with the mail server 5-2.

In step S40, the mail sending / receiving program 104 causes the USB interface 36 to disconnect from the mail server 5-2, and the process ends.

As described above, the PDA 1 communicates with the mail server 5-
From 2, it is possible to receive a mail addressed to the user of the PDA1.

Next, the mail sending / receiving program 104 and the interpreter 106, which are executed when the mail sending / receiving program 104 displays the received mail, are executed.
The script processing of the PDA 1 will be described with reference to the flowchart of FIG. In step S51, the mail sending / receiving program 104 reads the received mail 151.

In step S52, the mail transmission / reception program 104 determines whether or not the read mail 151 includes a script. If it is determined that the script is included, the process proceeds to step S53, where the interpreter 106 to start. Mail sending and receiving program 1
04 interprets the read mail 151 into the interpreter 106
To supply.

Note that the interpreter 106 may be activated in advance together with the mail transmission / reception program 104.

At step S54, the interpreter 1
The syntax analysis module 121 of 06 extracts a script included in the mail 151 based on the description of the mail 151. In step S55, the execution module 122 of the interpreter 106 executes the extracted script.

At step S56, the interpreter 1
The output module 123 executes display or audio output processing according to the result of the execution of the script. In step S57, the mail transmission / reception program 104 ends the interpreter 106, and the process ends.

If it is determined in step S51 that the script is not included, the processing corresponding to the script is not necessary, so that steps S53 to S5
7 is skipped, and the process ends.

As described above, when the script is included in the mail 151, the PDA 1 starts the interpreter 106 and executes the processing corresponding to the script.

The processing in step S52 is performed by the syntax analysis module 12 of the interpreter 106 that has been activated in advance.
1 may be executed.

Next, the Othello process, which is a more specific example of script execution, will be described with reference to the flowchart in FIG. In step S71, the mail sending / receiving program 104 reads the received mail 151.

In step S72, the mail transmission / reception program 104 activates the interpreter 106. In step S73, the output module 123 of the interpreter 106 causes the display unit 11 to display the Othello board and the frame.

In step S74, the execution module 122 determines whether or not a new hand has been input. If it is determined that no new hand has been input, the execution module 122 proceeds to step S74 until a new hand is input. And the process of the determination is repeated.

If it is determined in step S74 that a new hand has been input, the process proceeds to step S75, where the execution module 122 reads the coordinates of the new hand (indicating the position on the Othello board). In step S76, the execution module 122 determines whether the new hand satisfies the requirements specified in the Othello rule, and determines that the new hand satisfies the requirements specified in the Othello rule. If so, the flow advances to step S77 to place a frame at the position of the Othello board corresponding to the new hand.

In step S78, the execution module 122 updates the face of the frame, such as turning over a predetermined frame. In step S79, the output module 123
Displays the Othello board and the frame on the display unit 11.

[0189] In step S80, the output module 123 causes the USB interface 36 to communicate a new hand with the other party. In step S81, the mail sending / receiving program 104 ends the interpreter 106, and the process ends.

If it is determined in step S76 that the new hand does not satisfy the requirements specified in the Othello rule, the process proceeds to step S82, where the output module 12
3 displays an error on the display unit 11 to notify the user of the error, and the procedure returns to step S74 to repeat the process from the input of a new hand.

Thus, the PDA 1 executes Othello processing based on the script included in the mail 151.

As described above, when the user attempts to read the mail 151, the PDA 1 performs an action desired by the sender of the mail 151. When the user does not read the mail 151, the PDA 1 does not execute the script included in the mail 151, so that the processing load of the script can be minimized.

Since the PDA 1 can execute various processes corresponding to the description of the script only by executing the interpreter 106, the attached data is compared with the case where the data is attached to the mail and transmitted. There is no need to store a large number of application programs corresponding to the types.

Further, since the interpreter 106 executes the script, if the interpreter 106 is securely implemented, the processing can be executed more safely than when the execution program attached to the mail is executed as it is. .

Next, a more detailed configuration of the interpreter 106 will be described.

FIG. 30 is a diagram showing an example of a more detailed configuration of the interpreter 106. As shown in FIG.

Mail parsing section 502, decoder 503, parsing section 505, data forming section 517, encoder 518, and mail generating section 519 of FIG.
Corresponding to the syntax analysis module 121.

The script interpreter 506 in FIG.
Authentication encryption unit 507, resource access manager 50
8 and the storage module 511 correspond to the execution module 122 in FIG.

The I / O (Input / Output) module 510 in FIG. 30 corresponds to the output module 123 in FIG.

The mail transmission / reception program 104 supplies the mail 151 to be opened to the mail parsing unit 502 via the mail transmission / reception program plug-in interface 501, or acquires the mail 151 generated from the mail generation unit 519. I do.

The mail parsing unit 502 analyzes the syntax of the mail 151 supplied from the mail sending / receiving program 104 via the mail sending / receiving program plug-in interface 501, and extracts a script and data from the mail 151. Mail parsing unit 502
Supplies the script and data extracted from the mail 151 to the decoder 503.

A script is a type of program consisting of a series of instructions in which a processing procedure is described by character codes such as alphanumeric codes.

[0249] The decoder 503 decodes, for example, data encoded by a system such as Base64. Base64
Is an encoding method of binary data for converting data or a program into a sequence of 64 types of ASCII codes in order to transmit data or a program via a network transmitting only 7-bit data.

Note that the decoder 503 may decode the encoded script.

The decoder 503 is connected to the interface 50
4 to supply the script to the parsing unit 505,
The decrypted data is supplied to the script interpreter 506.

The syntax analysis unit 505 replaces a predetermined character string included in the script with an intermediate code that can be processed by the script interpreter 506. Here, when the intermediate code is roughly divided, generally,
(1) a lexical sequence such as a lexical analysis result or a generated lexical sequence; (2) a parse tree or a parse tree generated as a result of the parse analysis; a tree structure such as a Polish notation; (3) a triplet ,
The intermediate code is classified into a format similar to a machine language such as a virtual machine code called a four-tuple. In this specification, this intermediate code is used in the meaning of a parse tree.

In the Java (R) language, the above (3) is called "byte code".

The intermediate code is an intermediate format code that is temporarily created for convenience in the process of converting the original source code into a final executable format in the software program. By finely separating the conversion process from the source to the target in this way, it becomes easy to make the language processing system correspond to a plurality of platforms (targets).

For example, in Java (R), the source code is temporarily converted into an intermediate code called a byte code, and the converted intermediate code is stored in a WWW server. W
The WW server sends this bytecode to the WWW browser on the client side, and sends a Java (R) VM (Ja
va (R) Virtual Machine) interprets and executes the bytecode. In this case, the difference between each platform (CP
U and operating system differences), Java (R) VM
, The bytecode itself is not platform specific. In this way, a platform-independent program environment is realized in Java (R) while reducing the load imposed on execution (conversion from bytecode to executable code).

Also, in other high-level language compilers, instead of directly converting a source code into an execution program (usually a binary code that can be interpreted by a CPU), an intermediate code having a higher degree of abstraction than an actual machine is used. After conversion (there is no need to worry about the limitations of the actual machine architecture, etc., it is easy to optimize the code, etc.), and then a method of generating a final executable binary code is often used.

The syntax analyzer 505 supplies a script in which a predetermined character string is replaced with an intermediate code to the script interpreter 506.

The script interpreter 506 supplies the script to the authentication encryption unit 507, and the script
7 makes the script determine the validity.

The authentication encryption section 507 calculates a hash value corresponding to the script by applying a hash function such as MD (Message Digest) 5 to the script.
The authentication encryption unit 507 determines whether the calculated hash value and the data for authentication included in the script are the same.

FIG. 31 shows an example of a mail 151 including a script storing data for authentication.

In the mail 151 shown in FIG. 31, "<S
IGNATURE> ”and“ </ SIGNATURE> ”are data for authentication such as“ 347a9d8684ab96533fb6b51906fdacf9 ”.

[0262] An electronic signature or certificate may be stored in the mail 151, and the authentication encryption unit 507 may be authenticated based on the electronic signature or certificate.

If it is determined that the calculated hash value is the same as the authentication data, the authentication encryption unit 507 converts the data indicating that the script is valid, since the script has not been altered, into the script. It supplies to the interpreter 506.

If it is determined that the calculated hash value and the data for authentication are not the same, the authentication encryption unit 507 sends data indicating that the script is not valid, to the script interpreter 5, since the script has been modified.
06.

The script interpreter 506 sends the data indicating that the script is not valid to the authentication encryption unit 50.
When supplied from 7, do not execute the script.

In step 05, a predetermined character string of the script supplied from the decoder 503 is replaced with a character string that can be interpreted by the script interpreter 506. The syntax analysis unit 505 supplies the script in which a predetermined character string has been replaced to the script interpreter 506.

[0327] In step S508, the script interpreter 506 converts the script into an authentication encryption unit 507.
To make the authentication encryption unit 507 confirm the validity of the script. The authentication encryption unit 507 extracts, for example, authentication data included in the script supplied from the script interpreter 506, and generates a hash value by applying a hash function to the script.
The authentication encryption unit 507 determines the validity of the script based on whether the extracted authentication data and the generated hash value are the same.

The authentication encryption unit 507 supplies data indicating whether the script is valid or not to the script interpreter 506.

In step S509, the script interpreter 506 determines whether or not the script is valid based on the data supplied from the authentication encrypting unit 507. If the script is determined to be invalid, the script The process ends without executing the script because it has been modified.

[0330] If it is determined in step S509 that the script is valid, the flow advances to step S510, and the script interpreter 506 executes the script.

In step S511, the script interpreter 506 determines whether input / output, storage or reading of information, or access to an external application program has been requested by executing the script. If it is determined that storage or reading of information or access to an external application program has been requested, the process advances to step S512 to execute the script interpreter 506.
Causes the resource access manager 508 to execute input / output, storage or reading of information, or access of an external application program.

In step S513, the resource access manager 508 determines whether or not an input / output has been requested. If it is determined that the input / output has been requested, the process proceeds to step S514, where the I / O module 510 sends the input / output to the I / O module 510. Is displayed on the display unit 21 to determine whether or not to execute input / output based on the operation of the user.

[0333] If it is determined in step S514 that input / output is to be executed, the flow advances to step S515 to cause the resource access manager 508 to execute the I / O module 5
10 to execute input / output processing such as displaying an image, and the procedure proceeds to step S516.

If it is determined in step S513 that no input / output has been requested, no input / output processing is necessary, so that the processing in steps S514 and S515 is skipped, and the procedure proceeds to step S516.

If it is determined in step S514 that the input / output is not to be executed, the input / output processing must not be executed, and the processing in step S515 is skipped.
The procedure proceeds to step S516.

In step S516, the resource access manager 508 determines whether storage or reading of information has been requested. If it is determined that storage or reading of information has been requested, the process proceeds to step S517, where I / O is performed. A dialog box is displayed on the display unit 21 for allowing the user to input whether or not the module 510 is to store or read the information, and whether to store or read the information based on the operation of the user. Is determined.

If it is determined in step S517 that storage or reading of information is to be performed, the process proceeds to step S517.
Proceeding to 518, the resource access manager 508
The storage module 511 is caused to execute a process of storing or reading information, such as storing data in the Flash ROM 33, and the procedure proceeds to step S519.

If it is determined in step S516 that storage or reading of information has not been requested, the processing of storing or reading information is not necessary, and thus the processing of steps S517 and S518 is skipped, and the procedure proceeds to step S516. Proceed to S519.

If it is determined in step S517 that information storage or readout is not to be performed, information storage or readout processing must not be performed, so step S518 is skipped and the procedure proceeds to step S519. move on.

In step S519, the resource access manager 508 sets the schedule book program 5
12, it is determined whether or not access to an external application program such as the address book program 513, the memo pad program 514, the TODO book program 515, or the application program 516 is requested, and the access to the external application program is requested. If it is determined that the user has access to the external application program, the process proceeds to step S520, in which a dialog box is displayed on the display unit 21 for allowing the user to input whether to execute the access to the external application program. It is determined whether or not to access an external application program based on the operation.

If it is determined in step S520 that access to an external application program is to be executed, the process proceeds to step S521, where the resource access manager 508 accesses the external application program, and the procedure proceeds to step S522.

If it is determined in step S519 that access to the external application program has not been requested, access to the external application program is not required, and therefore step S520 is not necessary.
And the process of step S521 is skipped, and the procedure proceeds to step S522.

If it is determined in step S520 that the access to the external application program is not to be executed, the process of accessing the external application program must not be executed.
Step 21 is skipped, and the procedure proceeds to step S52.
Proceed to 2.

[0344] In step S522, the resource access manager 508 checks the script interpreter 50
6, the result of input / output, storage or reading of information, or access of an external application program is supplied.

In step S523, the script interpreter 506 determines whether or not to transmit the execution result of the script by e-mail based on the operation of the user or the description of the script, and transmits the execution result of the script by e-mail. If it is determined to transmit, step S524
The script interpreter 506 supplies the data constituting unit 517 with data that is attached to the electronic mail and needs to be formed into a predetermined format, such as data indicating the execution state of the script.

[0346] In step S525, the data forming unit 517 shapes the data supplied from the script interpreter 506 into a predetermined format. Data configuration unit 517
Supplies the molded data to the encoder 518 via the interface 504.

[0347] In step S526, the script interpreter 506 supplies a script or data to be attached to the electronic mail to the encoder 518 via the interface 504. The data that the script interpreter 506 directly supplies to the encoder 518 is data that does not need to be formed in the data configuration unit 517.

[0348] In step S527, the encoder 5
Reference numeral 18 encodes the data supplied from the data configuration unit 517 or the data supplied from the script interpreter 506 by, for example, a method such as Base64. The encoder 518 supplies the encoded data and the script to the mail generation unit 519.

At step S528, mail generating section 519 generates mail 151 with the script or data attached, based on the script or data supplied from encoder 518. The mail generation unit 519 includes the mail transmission / reception program plug-in interface 50
1, the generated mail 151 is supplied to the mail transmission / reception program 104.

In step S529, mail transmission / reception program 104 transmits mail 151 supplied from mail generation section 519, and the process ends.

If it is determined in step S511 that input / output, storage or reading of information, or access to an external application program is not requested, input / output, storage or reading of information, or access to an external application program are determined. Since the processing of step S512 is unnecessary, the processing of steps S512 to S522 is skipped, and the procedure proceeds to step S523 to determine whether or not to transmit the execution result of the script by e-mail.

If it is determined in step S523 that the execution result of the script is not transmitted by e-mail,
Since there is no need to send an e-mail, step S5
Steps S24 to S529 are skipped, and the process ends.

As described above, the interpreter 106 shown in FIG. 30 can extract the script attached to the mail 151 and execute it when trying to display the mail 151 to which the script is attached.

The interpreter 106 whose structure is shown in FIG.
When input / output, storage or reading of information, or access to an external application program is requested by execution of a script attached to the mail 151, the requested input / output, storage or reading of information, or external Of the application program can be executed.

The interpreter 1 shown in FIG.
06, when transmission of the execution result of the script by e-mail is requested, an e-mail 151 attached with the script or data can be transmitted according to the execution result of the script.

Next, with reference to the flowcharts of FIGS. 38 to 40, a description will be given of processing of executing a script stored in the script database 521 by the interpreter 106 having the configuration shown in FIG.

[0357] In step S601, the script launcher 520 stores the script in the script database 521 based on the input from the touch pad.
One script is selected from a script such as the Othello game script 531, the scheduled mail script 532, the ToDo mail script 533, the business card mail script 534, or the reminder mail script 535, and the selected script is analyzed through the interface 504. To the unit 505.

Steps S602 through S624 are performed in steps S507 through S5, respectively.
Since the processing is the same as each of the 29 processings, the description thereof is omitted.

As described above, the interpreter 106 shown in FIG. 30 can execute the selected and stored script.

The interpreter 106 whose structure is shown in FIG.
By executing the selected stored script, input / output, storage or reading of information, or when access to an external application program is requested, the requested input / output, storage or reading of information, Alternatively, access to an external application program can be performed.

The interpreter 1 shown in FIG.
06 is a mail 15 attached with a script or data by executing the selected and stored script.
1 can be sent.

Next, the processing of executing the script attached to the e-mail described with reference to the flowcharts of FIGS. 35 to 37 and the processing of executing the script described with reference to the flowcharts of FIGS. 38 to 40 will be described. A specific example of the processing will be described.

For example, in a mail transmitted by an organizer of an event such as a meeting or a drinking party, a scheduler that can execute the PDA 1, the personal computer 3, or the camera-equipped digital mobile phone 301 of the mail recipient (for example, FIG. 30) Schedule book program 512
And the like, the schedule at a predetermined date and time is confirmed from the schedule data recorded by the process, and the result is displayed, and a reply indicating whether or not the mail recipient participates in a new event is transmitted. Script can be attached. Here, the mail to which such a script is attached is referred to as a scheduled mail.

At step S601 in FIG. 38, the script launcher 520
1, the scheduled mail script 532 is read out, and the processes of steps S602 to S605 are executed. In step S605, the scheduled mail script 532 is read.
Is determined to be valid, a scheduled mail creation screen shown in FIG. 41 is displayed. On the scheduled e-mail creation screen, the user can enter the destination of the e-mail, the destination of the carbon copy (CC), the subject of the e-mail, the event name (including the reply deadline designation date and time), the date and time, the location, and the comment. ing.

In order for the user to display the scheduled mail creation screen, for example, on the initial display screen of the Palm OS shown in FIG. "schedule"
By tapping the icon with
The schedule book program 512 is started, and as shown in FIG. 42, an item of “scheduled mail creation” is selected from the menu 621 on the execution screen of the schedule book program 512, or the initial display screen shown in FIG. , By tapping the icon described as “mail”, the mail sending / receiving program 10
43, and an operation of selecting an item of “scheduled mail” from the menu 631 on the execution screen of the mail transmission / reception program 104 as shown in FIG.

Referring to the flowchart of FIG. 44, FIG.
As a specific example of the processing from step S605 in FIG. 8 to step S617 in FIG. 39, the creation processing of the scheduled mail will be described. Here, the description will be made assuming that the scheduled mail is created on the PDA 1 on which the Palm OS is mounted. For example, the personal computer 3 and the camera-equipped digital cellular phone 30
1 and the like, basically the same processing is executed when a scheduled mail is created.

The user who wants to send the scheduled mail is shown in FIG.
Since the above-described operation is performed to display the scheduled e-mail creation screen described using, the script interpreter 506 transmits the I / O module 510, the platform resource access interface 509, and the resource access manager 508 in step S641. Via the touch pad control unit 38 or the jog dial 23, an operation input for displaying the scheduled mail creation screen described with reference to FIG. 41 is generated, and a control signal for displaying the scheduled mail creation screen is generated. Output to the resource access manager 508. The resource access manager 508 causes the I / O module 510 to display the scheduled mail creation screen shown in FIG.

The user refers to the screen for creating a scheduled mail displayed on the display unit 21 and fills in blanks with necessary information. In step S642, the script interpreter 506 sends the destination (including the CC), the subject, and the like to be entered by the user from the touch pad control unit 38 via the I / O module 510, the platform resource access interface 509, and the resource access manager 508. Event name (including the deadline specified date and time),
Receive input for date and time, location, and comments.

In step S643, script interpreter 506 reads the script attached to the mail to be transmitted, and outputs it to mail generating unit 519 via interface 504 and encoder 518 together with the input data. The script read here is the scheduled mail script 532 being executed.
May be included, or may be recorded in the script database 521.

In step S644, mail generating section 519 attaches the script and the input data to the mail, and generates a scheduled mail in the form of mail 151 including the script as described with reference to FIG.

In step S645, the mail generation unit 519 determines a process ID, which is a unique number, for each scheduled mail, and associates the process ID with the mail 151 created in step S644.
Proceeding to 618, the scheduled mail is transmitted by the subsequent processing.

By the processing described with reference to FIG. 44, a mail to which a script for automatically checking the mail recipient's schedule and returning whether or not to participate in the event is created is created.

Next, with reference to the flowcharts of FIGS. 45 and 46, the PDA 1 that has received the scheduled mail generated by the processing described with reference to the flowchart of FIG.
Are the same as the steps S510 to S37 in FIG.
A script execution process will be described as a specific example of the process executed in 529.

In step S671, the script interpreter 506 executes the show () method of the script extracted in step S503 in FIG.
A control signal for displaying the body of the received mail is generated and output to the resource access manager 508. The resource access manager 508 causes the I / O module 510 to display the text of the received mail on the display unit 21.

FIG. 47 shows an example of the displayed mail. The e-mail includes the subject set in step S642 in FIG. 44 and the designated date and time for reply (in the case of FIG. 47,
Event name including "January 7"), date and time, place, and comment are described.

[0376] In step S672, the script interpreter 506 causes the resource access manager 50
8 causes the schedule database managed by the schedule book program 512 to be accessed via the storage module 511, and the schedule at the date and time specified in the script is extracted from the recorded schedules.

[0377] In step S673, the script interpreter 506 determines whether or not the schedule at the designated date and time is vacant based on the schedule extracted in step S672.

If it is determined in step S673 that the schedule for the specified date and time is vacant,
In step S674, the script interpreter 5
06 generates a control signal for displaying a dialog box in which a message for confirming that the event specified in the received scheduled mail is to be scheduled is described, and outputs the control signal to the resource access manager 508. The resource access manager 508 has I / O
A module 510 displays a dialog box on the display unit 21.
To be displayed.

FIG. 48 shows an example of the dialog box 641 displayed. The dialog box 641 includes, for example, a message “The schedule is vacant. Would you like to participate?”, A YES button 642 selected when participating in the event specified by e-mail, and a selection when not participating in the event NO button 643 is displayed. If the script runs out of time,
If the schedule is set to be forcibly entered, for example, a message “The schedule is vacant. Please join” is displayed in the dialog box 641, and the NO button 643 is not displayed. May be.

[0380] In addition, the user may be allowed to write a predetermined comment as necessary. That is, if the user has no schedule at this time, but has not confirmed a clear schedule, such as receiving a consultation for participation in another event, before selecting the YES button 642, for example, You may be able to enter a comment such as "I am participating at this time, but it is not clear."

Note that the display of the dialog box 641 is performed after a certain period of time has elapsed so that the user can sufficiently read the contents described in the mail.

[0382] In step S675, the script interpreter 506 sends the I / O module 510, platform resource access interface 509,
Then, it is determined whether or not the YES button 642 has been selected based on a signal indicating a user operation input from the jog dial 23 or the touch pad control unit 38 via the resource access manager 508. Step S6
If it is determined at 75 that the YES button 642 has been selected, the process proceeds to step S681 described below, and if it is determined that the YES button 642 has not been selected, the process proceeds to step S684 described below.

[0383] If it is determined in step S673 that the schedule at the designated date and time is not vacant, in step S676, the script interpreter 506 determines, based on the schedule extracted in step S672, the existing schedule. Content,
And generating a control signal for causing the user to display a dialog box in which a message for prompting the user to select one of the already entered event and the event described in the received e-mail, Output to the resource access manager 508. The resource access manager 508 causes the I / O module 510 to display a dialog box on the display unit 21.

FIG. 49 shows an example of the dialog box 651 displayed in step S676. In the dialog box 651, for example, "A meeting with Hanako" is scheduled. Change event? And a YES button 652 selected when changing the schedule and a NO button 653 selected when not changing the schedule.

[0385] As described above, the display of the dialog box 651 is performed after a certain period of time has elapsed such that the user can sufficiently read the contents described in the mail.

In step S677, script interpreter 506 is instructed to change the schedule based on a signal indicating a user operation input from jog dial 23 or touch pad control unit 38 (ie, YES button in FIG. 49). 652 has been selected).

If it is determined in step S677 that a schedule change has been instructed, step S67 is performed.
8, the script interpreter 506 causes the resource access manager 508 to access the schedule database managed by the schedule book program 512 via the storage module 511, and cancels the schedule (“Hanako” scheduled first) Meeting with ""
Event) is determined to be a schedule entered by the scheduled mail.

If it is determined in step S678 that the schedule to be canceled is the schedule entered by the scheduled mail, the process proceeds to step S679.
In the script interpreter 506, the resource access manager 508
11 to access the address book database managed by the address book program 513, extract the e-mail address of the request source of the schedule to be canceled, generate an e-mail indicating that the schedule is cancelled, and To the schedule requester.

That is, the script interpreter 506
Creates an e-mail with a message such as "I'm sorry, the appointment will be canceled from 18:00 on January 8", and sends it to the resource access manager 508 via the storage module 511. In the address book database stored in the Flash ROM 33, the user is requested to search for the email address of the requester of the schedule to be canceled.
18. The generated mail is output to the mail transmission / reception program 104 via the mail generation unit 519 and the mail transmission / reception program plug-in interface 501. The mail sending / receiving program 104 sends the input mail to the requester of the schedule to be canceled.

If it is determined in step S678 that the schedule to be canceled is not the schedule entered by the scheduled mail, the process proceeds to step S68.
At 0, the script interpreter 506 generates a confirmation message of the schedule to be canceled, generates a control signal for displaying a dialog box describing the message, and outputs the control signal to the resource access manager 508. Resource Access Manager 5
08 causes the I / O module 510 to display a dialog box on the display unit 21.

That is, the script interpreter 506
Generates a message such as “Cancel the schedule of“ meeting with Mr. Hanako ”from 18:00 on January 8” and causes the I / O module 510 to output the message by the processing of the resource access manager 508. I / O
The module 510 causes the display unit 21 to display a dialog box in which a message generated by the script interpreter 506 is described.

If it is determined in step S675 that YES button 642 has been selected, step S67
9 or after the processing in step S680, in step S681, the script interpreter 506 generates a control signal for creating a reply mail for notifying that a schedule is to be created, and Output to the mail generation unit 519 via the encoder 518. The mail generation unit 519
Factor to participate (eg 0) and process ID
Is generated as data, and a mail including a comment entered as necessary is generated and output to the mail transmission / reception program 104 via the mail transmission / reception program plug-in interface 501.

In step S682, the mail sending / receiving program 104 returns the reply mail created in step S681. In step S683, the script interpreter 506 causes the resource access manager 508 to access the schedule database managed by the schedule book program 512 via the storage module 511 and update the schedule at the corresponding date and time (that is, update the new event). Register on schedule).

If it is determined in step S675 that YES button 642 has not been selected, or if it has been determined in step S677 that a change in schedule has not been instructed, step S684
In, the script interpreter 506 generates a control signal for generating a reply mail for rejecting the schedule, and outputs the control signal to the mail generation unit 519 via the interface 504 and the encoder. Mail generator 51
Reference numeral 9 denotes a mail including a factor (for example, 1) indicating non-participation and a process ID as data, further generating a mail including a comment entered as necessary, and transmitting the mail via the mail transmitting / receiving program plug-in interface 501 Output to the transmission / reception program 104. In step S685, the mail sending / receiving program 104
Causes the reply mail created in step S684 to be returned.

Step S683 or step S68
After the end of the process of step 5, in step S686, the script interpreter 506 generates a control signal for displaying a dialog box indicating the end of the process, and outputs the control signal to the resource access manager 508. The resource access manager 508 controls the I / O module 510
Then, a dialog box is displayed on the display unit 21 and the process is terminated.

FIG. 50 shows a display example of a dialog box 661 indicating the end of the processing. When an event is added at a scheduled date and time, as shown in FIG.
For example, "Mr. Ando (sender of the scheduled e-mail)
Dialog box 661 is displayed with the message "Reply to the schedule."

On the other hand, a schedule mail for adding an event matching the scheduled date and time to the schedule is received, and the schedule first entered is prioritized (that is, the event of the schedule mail is rejected). ),
In the dialog box 661, for example, a message “Replying to Mr. Ando (sender of the scheduled mail) that he / she cannot participate” is described, and the event described in the scheduled mail is prioritized (that is, first, If the scheduled event has been cancelled), the dialog box 661 will display, for example, "A reply to the participation was sent to Mr. Ando (sender of the scheduled email) and the event was scheduled. I sent you an email. "

The PDA 1 that has received the mail returned in the processing described with reference to FIGS. 45 and 46 executes a script based on the process ID and the factor included in the reply to create or update a reply list. I do. next,
Referring to the flowchart of FIG. 51, PDA 1 that has received the reply to the scheduled mail is sent to step S605 of FIG.
Reply list creation / update processing will be described as a specific example of the processing executed in step S617 of FIG.

At step S701, the same processing as at step S671 in FIG. 45 is executed.

For example, as shown in FIG. 52, for example, as shown in FIG. 52, the reply e-mail notifying of participation in the event is “I (responder of the scheduled e-mail) is willing to send the following drinking party (event name) I would like to participate ", the start date and time of the event, and the location of the event. On the other hand, in the reply e-mail notifying of the absence from the event, for example, "I (responder of the scheduled e-mail) is sorry, but I would like to be absent from the following drinking party (event name) I think"
Message, the start date and time of the event, and the location of the event. Also, as needed, the respondents filled in the information, for example, "I am participating at this time but it is not clear" or "I am on a business trip abroad,
The following drinking party (event name) cannot be absent. "

[0401] In step S702, the script interpreter 506 reads the process ID attached to the received mail, and in step S703, reads the process ID.
For example, the memo pad program 514 in FIG.
It is determined whether there is a reply list of the corresponding process ID created by an application program such as a text editor). Here, the reply list is described as being created by the memo pad program 514, which is the basic application software of Palm OS, but the reply list may be generated by another application program.

If it is determined in step S703 that a reply list with the corresponding process ID exists,
In step S704, the script interpreter 5
06 generates a control signal for updating the reply list of the corresponding process ID based on the attached factor, and sends the control signal to the memo pad program 514 via the resource access manager 508 and the platform resource access interface 509. Output. The memo pad program 514 updates the reply list of the corresponding process ID according to the control signal (enters the attendance status such as ○ or ×, writes a comment, etc.), and the process returns to step S618 in FIG. In the processing, FIG.
In step S618, it is determined that the execution result of the script is not transmitted by e-mail).

If it is determined in step S703 that the reply list of the corresponding process ID does not exist, the process proceeds to step S705, where the script interpreter 506 stores the reply list of the corresponding process ID as a file by the memo pad program 514. , A control signal for causing the resource access manager 508 and the platform resource access interface 509 to newly generate
To the memo pad program 514 via the. The memo pad program 514 newly creates a reply list of the corresponding process ID according to the control signal, and the process returns to step S618 in FIG. 40 (in this process, in step S618 in FIG. 40, the execution result of the script is It is determined not to send by e-mail.)

FIG. 53 shows an example of the reply list. The reply list is created in a file format generated by the memo pad program 514. This reply list is displayed, for example, by tapping the reply status button 671 in FIG. 52, or on the initial screen described with reference to FIG. Can be displayed by selecting a file.

[0405] As described above, the organizer transmits the scheduled mail to a plurality of users, and sequentially updates the reply list when the reply mail is received from the recipient of the scheduled mail.
You can easily know the participation status of the event.

According to the processing described with reference to FIG. 51, when the reply mail is received, the memo pad program 514 updates the reply list of the corresponding process ID according to the control signal from the script interpreter 506 (ie, , Update the participation status). However, with regard to e-mails that have not been received yet, it is not possible to grasp the participation status of the event, and there is a risk that the e-mails that should have been transmitted may be lost on the Internet 4 (in other words, e-mails Is not guaranteed), it is desirable to be able to take some action for a user who does not make a reply even after the reply deadline has passed.

[0407] A process of transmitting a reminder mail as a means for executing any action to a user who does not make a reply even after the reply deadline of the transmitted scheduled mail has passed will be described.

First, the scheduled mail transmitted by the event organizer is created by the scheduled mail creation processing described with reference to FIG. 44. In step S642, the script interpreter 506 prompts the user to specify the reply deadline. When the input of the date and time (for example, January 7) is received, a control signal for requesting that an event for generating a reminder mail be generated when the reply deadline specified date and time has elapsed is generated, Resource Access Manager 5
08 and the platform resource access interface 509 to the application program 516.

[0409] The application program 516 operates in accordance with a control signal from the script interpreter 506.
Judge whether the specified date and time has come (expiration date management),
