Description

  The present invention relates to a screen recording program, and more particularly to a screen recording program for recording a screen on a host terminal that performs processing in cooperation with a host computer.

  For example, a host computer (mainframe) is used in a terminal (dedicated hardware) dedicated to the host computer. In recent years, it has become the mainstream to use an application in which the function of a terminal dedicated to a host computer is realized by software emulation on a PC.

  Such an application on a PC is generally called a host terminal emulator. In the following description, a terminal dedicated to a host computer and a host terminal emulator are collectively referred to as a host terminal.

  FIG. 1 is a configuration diagram of an example of a system including a host computer and a host terminal. In the system 1 of FIG. 1, a host computer 10 and a plurality of host terminals 11A to 11C are connected via a dedicated line, a public line, a network such as the Internet or a LAN. When any of the host terminals 11A to 11C is acceptable, it is simply referred to as the host terminal 11.

  On the display device of the host terminal 11, a screen of an application (host application) operating on the host computer 10 is displayed as shown in FIG. Processing of the host application proceeds by an input operation of an operator who operates the host terminal 11, and the screen displayed on the host terminal 11 changes.

  FIG. 2 is an image diagram showing the transition of the screen displayed on the host terminal. FIG. 2 shows a state in which the screen displayed on the host terminal 11 transitions in the order of the screens 21, 22, and 23.

  In the business using the host terminal 11, the operator performs an input operation to the input field of the screen displayed on the host terminal 11. If the task is to repeat the input over and over multiple screens, you may want to input with reference to the contents of the past screen. In such a case, generally, when a screen to be referred to later is displayed on the host terminal 11, the operator records image data or text data of the screen.

  When recording the image data, the operator records the image data of the screen displayed on the host terminal 11 (hereinafter referred to as the host terminal screen) using the screen recording function of the OS, and records the file of the image editing application. The function records the image data of the host terminal screen in a file and reuses it.

  For example, in the case of Windows (registered trademark), the image data of the host terminal screen is recorded by pressing the [Print Screen] key, and the image data is recorded in a file by a paint file recording function as an example of an image editing application, and then replayed. Use.

  When text data is to be recorded, the operator uses the software function (copy and paste) of the host terminal 11 to output character information on the host terminal screen as text data, for example, a Windows (registered trademark) memo pad or the like. Record the text data of the host terminal screen in a file with the file recording function of the text editor and reuse it.

  FIG. 3 is an image diagram of an example of image data and text data recorded by the operator. For example, when the screen to be referred to later is displayed on the host terminal 11, the operator records the image data 31 or text data 32 of the screen. The operator can input to the input field of the host terminal screen displayed on the host terminal 11 later by referring to the image data 31 or by copying and pasting the text data 32.

Japanese Patent Application Laid-Open No. 2004-228561 describes contents for storing image information of a terminal connected to a host computer in response to a predetermined request.
JP-A-5-224633

  In the conventional host terminal 11, when the screen is recorded, the operation differs between when acquiring the image data and when acquiring the text data, and there are a plurality of functions of the OS for recording or referencing the screen. In combination, the operator must perform the operation manually, which complicates the operation. For this reason, the conventional host terminal 11 has a problem that the burden on the operator who frequently records or refers to the screen is heavy. Further, the conventional host terminal 11 has a first problem that it takes time to manage the acquired image data and text data (recording location, search and deletion of image data and text data).

  Further, in the case of a host application that automatically and continuously updates the screen on the host terminal 11 in the conventional host terminal 11, there is a second problem that it is difficult to record the screen at an appropriate timing. .

  Further, in the conventional host terminal 11, the screen referred to immediately before or the input data has been lost due to the disconnection with the host computer 10 due to a network abnormality, the erroneous operation of the host terminal 11, or the software abnormality. There was a third problem of being broken.

  Although the above cited reference 1 solves the first problem, it cannot solve the second and third problems. For example, when a screen is recorded every predetermined time, there is a problem that a screen in the middle of updating is recorded when the predetermined time is reached during the updating of the screen.

  Further, in the case of a host application that automatically and continuously updates the screen on the host terminal 11, if the frequency of recording the screen is increased, the same screen is duplicated and the recording device and CPU are wasted. There was a problem of wasting. On the other hand, if the frequency of screen recording is reduced, a necessary screen may not be recorded.

  Furthermore, when recording a screen every predetermined time, when communication with the host computer 10 is disconnected due to a network abnormality or the like, it is examined what processing was performed on the screen immediately before the communication was disconnected. However, there is a problem that the screen when the communication with the host computer 10 is disconnected may not be recorded with good timing.

  The present invention has been made in view of the above points, and an object thereof is to provide a screen recording program capable of recording a screen on a host terminal that performs processing in cooperation with a host computer with good timing.

In order to solve the above-described problems, the present invention is a screen recording program executed in a host terminal including a recording device and an arithmetic processing device, and a host that performs processing in cooperation with the arithmetic processing device when a predetermined time elapses. In the confirmation step of confirming reception completion of image data from the computer with reference to the reception completion information of the image data from the host computer held in the host terminal, in the confirmation step, from the host computer When it is confirmed that the image data has been received, the recording device executes the process of recording the received image data on the recording device and displays the received image data to confirm that the image data has been received from the host computer. If no, display the image data is not completed the reception without recording in the recording device Characterized in that it is a screen recording program which comprises a recording display step of causing, the.

In the recording and displaying step, when it is confirmed in the checking step that reception of image data from the host computer is completed, at least one of image data stored in a screen buffer and text data corresponding to the image data is stored in the recording device. It is good also as performing the process recorded on this.

  A screen data list window display step of displaying the image data and text data recorded in the recording device as a list after adding information on the timing at which the image data and text data were recorded is further executed. Also good.

  In the screen data list window display step, the image data and text data are enlarged and displayed in response to a click on the image data and text data listed on the screen data list window. It is good.

  As described above, according to the present invention, it is possible to provide a screen recording program capable of recording a screen on a host terminal that performs processing in cooperation with a host computer with good timing.

  Next, the best mode for carrying out the present invention will be described based on the following embodiments with reference to the drawings. In the following embodiments, a host terminal using a host terminal emulator will be described as an example. However, a terminal dedicated to the host computer may be used.

  FIG. 4 is a block diagram of an embodiment of a system including a host computer and a host terminal according to the present invention. In the system 1, a host computer 10 and a plurality of host terminals 11 are connected through a dedicated line, a public line, a network such as the Internet or a LAN.

  The host terminal 11 includes an arithmetic processing device 41, a communication device 42, an input device 43, a display device 44, and a recording device 45. The input device 43 is composed of a keyboard, a mouse, etc., and is used for inputting various signals. The display device 44 is composed of a display or the like, and is used for displaying various windows and screens of data. The recording device 45 is configured by a memory, a hard disk device (HDD), or the like, and is used for recording screen image data or text data. The communication device 42 includes a modem, a LAN card, and the like, and is used for connecting to a network.

  The arithmetic processing unit 41 executes an OS 50 and a host terminal emulator 51. The arithmetic processing unit 41 executes a host terminal emulator 51 to realize a recording control function 61, a display control function 62, a terminal control function 63, and a communication control function 64. The host terminal emulator 51 is an example of a screen recording program according to the present invention.

  The terminal control function 63 is a central function that controls the overall operation of the host terminal 11. The communication control function 64 is a function for receiving data from the host computer 10 and supplying the data to the terminal control function 63 and transmitting the data supplied from the terminal control function 63 to the host computer 10.

  The display control function 62 is a function for updating the content held in the screen buffer 72 in accordance with an instruction from the terminal control function 63 and requesting the display device 44 to display the content held in the screen buffer 72. The recording control function 61 refers to the data processing status information 73, which is information held by the terminal control function 63, and the contents held in the screen buffer 72 of the display control function 62, and whether or not the designated recording condition is satisfied. And the recording device 45 records the content held in the screen buffer 72 at an appropriate timing to be described later. The recording control function 61 uses the recording condition determination processing unit 71 to determine whether or not the specified recording condition is satisfied.

  The host terminal emulator 51 is at least a part of various programs that control the host terminal 11. The host terminal emulator 51 is provided, for example, by distributing a recording medium or downloading from a network. The recording medium on which the host terminal emulator 51 is recorded is information such as a CD-ROM, a flexible disk, a magneto-optical disk, etc., a recording medium for recording information optically, electrically or magnetically, a ROM, a flash memory, etc. Various types of recording media, such as a semiconductor memory that electrically records data, can be used.

  The host terminal emulator 51 is installed in the recording device 45, for example. The host terminal 11 stores the installed host terminal emulator 51 and also stores necessary files, data, and the like. Then, the arithmetic processing unit 41 reads the host terminal emulator 51 of the recording device 45 and executes the host terminal emulator 51.

  The host terminal 11 displays, for example, host application screens 21 to 23 as shown in FIG. 2 that operate on the host computer 10. Processing of the host application proceeds by an input operation of an operator who operates the host terminal 11, and the screen displayed on the host terminal 11 changes. The host terminal 11 determines whether a specified recording condition (a certain time has elapsed, reception of a specific command from the host computer 10, input of a specific command to the host terminal 11, disconnection of communication) is satisfied, The screen image data held in the screen buffer 72 or text data corresponding to the image data is recorded in the recording device 45 at an appropriate timing according to the designated recording condition.

  FIG. 5 is a flowchart showing an example of the procedure of the screen recording process when the designated recording condition is a certain time. In step S1, the terminal control function 63 determines whether a recording request has been received. If no recording request has been received, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72.

  In step S <b> 2, the display control function 62 updates the contents held in the screen buffer 72 in accordance with an instruction from the terminal control function 63. In step S3, the display control function 62 requests the display device 44 to display the contents held in the screen buffer 72, updates the host terminal screen displayed on the display device 44, and then proceeds to step S4. If the endless loop continues, the terminal control function 63 returns to step S1. Further, the terminal control function 63 ends the process if the infinite loop is not continued.

  On the other hand, if a recording request has been received, the terminal control function 63 proceeds to step S5 and determines the lapse of a fixed time by a timer process. If the predetermined time has not elapsed, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and to proceed to the process of step S2. .

  If the predetermined time has elapsed, the terminal control function 63 proceeds to step S6, refers to the data processing status information 73, and determines whether or not reception of image data from the host computer 10 has been completed. If the reception of the image data has not been completed, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and the process of step S2 is performed. Advance.

  On the other hand, if the reception of the image data is completed, the terminal control function 63 instructs the recording control function 61 to record the screen data. In step S 7, the recording control function 61 records screen image data held in the screen buffer 72 or text data corresponding to the image data in the recording device 45. Thereafter, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and to proceed to the process of step S2.

  As described above, according to the flowchart of FIG. 5, even when the screen is recorded at regular time intervals, even if it is time to record the screen during the screen update, the screen being updated may be recorded. The screen after the completion of the update can be recorded by recording the screen after the reception of the image data is completed.

  FIG. 6 is a flowchart illustrating an example of the procedure of screen recording processing when the designated recording condition is reception of a specific command from the host computer. First, in step S11, the terminal control function 63 determines whether a recording request has been received. If no recording request has been received, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72.

  In step S 12, the display control function 62 updates the contents held in the screen buffer 72 in accordance with an instruction from the terminal control function 63. In step S13, the display control function 62 requests the display device 44 to display the contents held in the screen buffer 72, updates the host terminal screen displayed on the display device 44, and then proceeds to step S14. If the endless loop continues, the terminal control function 63 returns to step S11. Further, the terminal control function 63 ends the process if the infinite loop is not continued.

  On the other hand, if a recording request has been received, the terminal control function 63 proceeds to step S15, and determines whether or not a specific command (for example, one indicating screen update or rewriting) has been received from the host computer 10. For example, the terminal control function 63 refers to the data processing status information 73 and determines whether a specific command has been received. The terminal control function 63 may refer to the screen buffer 72 of the display control function 62 to determine whether a specific command has been received.

  If a specific command has not been received, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and the process proceeds to step S12. Make it.

  If a specific command has been received, the terminal control function 63 proceeds to step S16 and refers to the data processing status information 73 to determine whether or not reception of image data from the host computer 10 has been completed. If the reception of the image data has not been completed, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and the process of step S12 is performed. Advance.

  On the other hand, if the reception of the image data is completed, the terminal control function 63 instructs the recording control function 61 to record the screen data. In step S 17, the recording control function 61 records screen image data held in the screen buffer 72 or text data corresponding to the image data in the recording device 45. Thereafter, the terminal control function 63 instructs the display control function 62 to update the content held in the screen buffer 72 and display the content held in the screen buffer 72, and to proceed to the process of step S2.

  As described above, according to the flowchart of FIG. 6, when a specific command indicating screen updating or rewriting is received from the host computer 10, the screen is recorded after the reception of the image data is completed. The screen after the update is completed can be recorded without recording the screen. When a specific command indicating screen updating or rewriting is received from the host computer 10, the terminal control function 63 may record the screen before executing the received specific command.

  In addition, according to the flowchart of FIG. 6, since a screen is recorded when a specific command indicating screen update or rewrite is received, a screen that has changed is recorded, and the same screen is recorded in duplicate. The recording apparatus and CPU are not wasted.

  FIG. 7 is a flowchart of an example showing the procedure of the screen recording process when the designated recording condition is input of a specific command to the host terminal 11. In step S21, the terminal control function 63 determines whether a recording request has been received. If no recording request has been received, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72.

  In step S22, the display control function 62 updates the contents held in the screen buffer 72 in accordance with an instruction from the terminal control function 63. In step S23, the display control function 62 requests the display device 44 to display the contents held in the screen buffer 72, updates the host terminal screen displayed on the display device 44, and then proceeds to step S24. If the infinite loop continues, the terminal control function 63 returns to step S21. Further, the terminal control function 63 ends the process if the infinite loop is not continued.

  On the other hand, if a recording request is received, the terminal control function 63 proceeds to step S25, and determines whether or not a specific command or a specific key (for example, pressing of the [ENTER] key) is input to the input device 43. For example, the terminal control function 63 refers to the data processing status information 73 and determines whether a specific command or a specific key indicating screen update or rewrite has been input.

  If a specific command or a specific key has not been input, the terminal control function 63 instructs the display control function 62 to update the content held in the screen buffer 72 and display the content held in the screen buffer 72, step S22. Proceed to processing.

  If a specific command or a specific key has been input, the terminal control function 63 proceeds to step S26, refers to the data processing status information 73, and determines whether or not reception of image data from the host computer 10 has been completed. to decide. If the reception of the image data has not been completed, the terminal control function 63 instructs the display control function 62 to update the content held in the screen buffer 72 and display the content held in the screen buffer 72, and the process of step S22 is performed. Advance.

  On the other hand, if the reception of the image data is completed, the terminal control function 63 instructs the recording control function 61 to record the screen data. In step S 27, the recording control function 61 records screen image data held in the screen buffer 72 or text data corresponding to the image data in the recording device 45. Thereafter, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and to proceed to the process of step S22.

  As described above, according to the flowchart of FIG. 7, when a specific command or key is input from the input device 43, the screen during the update is recorded by recording the screen after the reception of the image data is completed. You can record the screen after the update is complete. When a specific command or key is input from the input device 43, the terminal control function 63 may record a screen before executing the input command or key.

  In addition, according to the flowchart of FIG. 7, since a screen is recorded when a specific command or key indicating screen update or rewrite is input, a screen that has changed is recorded, and the same screen is displayed. Are not redundantly recorded, and the recording apparatus and CPU are not wasted.

  FIG. 8 is a flowchart showing an example of a screen recording process procedure when the designated recording condition is communication disconnection. First, in step S31, the terminal control function 63 determines whether a recording request has been received. If no recording request has been received, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72.

  In step S32, the display control function 62 updates the contents held in the screen buffer 72 in accordance with an instruction from the terminal control function 63. In step S33, the display control function 62 requests the display device 44 to display the contents held in the screen buffer 72, updates the host terminal screen displayed on the display device 44, and then proceeds to step S34. If the infinite loop continues, the terminal control function 63 returns to step S31. Further, the terminal control function 63 ends the process if the infinite loop is not continued.

  On the other hand, if a recording request has been received, the terminal control function 63 proceeds to step S35 and determines whether or not communication with the host computer 10 has been disconnected. For example, the terminal control function 63 refers to the data processing status information 73 and determines whether communication with the host computer 10 is disconnected.

  If the communication with the host computer 10 has not been disconnected, the terminal control function 63 instructs the display control function 62 to update the contents held in the screen buffer 72 and display the contents held in the screen buffer 72, and in step S32 Proceed to processing.

  If the communication with the host computer 10 is disconnected, the terminal control function 63 instructs the recording control function 61 to record the screen data. In step S 36, the recording control function 61 records screen image data held in the screen buffer 72 or text data corresponding to the image data in the recording device 45. That is, the recording control function 61 records screen image data held in the screen buffer 72 or text data corresponding to the image data before the screen update occurs.

  Thereafter, the terminal control function 63 instructs the display control function 62 to update the content held in the screen buffer 72 and display the content held in the screen buffer 72, and to proceed to the process of step S32.

  As described above, according to the flowchart of FIG. 8, when the communication between the host computer 10 and the host terminal 11 is disconnected for some reason, the screen immediately before the communication is disconnected can be recorded. For example, when the communication between the host computer 10 and the host terminal 11 is disconnected for some reason, there is a case where it is desired to examine the screen immediately before the communication is disconnected, but the communication is disconnected only by recording the screen every predetermined time. The problem that the screen just before being recorded cannot be recorded in a timely manner is solved.

  Further, according to the flowchart of FIG. 8, when the communication between the host computer 10 and the host terminal 11 is disconnected, the screen immediately before the communication is disconnected can be recorded. Therefore, the screen need not be recorded every predetermined time. The screen immediately before the disconnection of communication can be recorded with good timing, the same screen is not recorded repeatedly, and the recording device and CPU are not wasted.

  Hereinafter, an embodiment of the host terminal 11 according to the present invention will be described in detail. For example, the host terminal 11 has functions such as manual recording, automatic recording, automatic deletion of screen automatic recording data, reference of screen contents, and display of screens.

  In the manual recording function, when the screen to be recorded is displayed on the display device 44, the operator clicks a specific button (icon), operates a specific key, and selects [screen recording] from the menu. Thus, the screen (image data, text data) is recorded and stored in a recording device 45 such as a storage on the host terminal 11. In addition, at the time of storage, the stored time is added as information.

  The automatic recording function defines (specifies) various recording conditions in advance, records a screen at a timing according to the recording conditions, and stores the screen in the recording device 45 on the host terminal 11. In addition, at the time of storage, the stored time is added as information. The recording conditions include the timing at which the operator of the host terminal 11 inputs a specific key or specific data, the timing at which specific data (character string) is received from the host computer 10, a certain time interval, and a certain amount of data. There are timing, timing when the logical session with the host computer 10 is disconnected, timing when the line is disconnected, and the like.

  If the timing when the operator of the host terminal 11 inputs a specific key or specific data is the recording condition, the display device 44 is at the timing when the operator of the host terminal 11 inputs the specific key or specific data. Record the screen displayed in. For example, input of a specific key includes pressing of [Enter] key, pressing of [Data clear] key, and the like.

  When the [Enter] key is pressed, a screen in which the operator has completed inputting various data is recorded, and this screen can be used later when it is desired to refer to the input content. When the [DATA CLEAR] key is pressed, the screen immediately before the input data is cleared is recorded, and this screen recovers when the [DATA CLEAR] key is accidentally pressed (later, You can refer to lost input data).

  If the timing at which the specific data (character string) is received from the host computer 10 is the recording condition, immediately before the specific data (character string) is received at the timing at which the specific data (character string) is received from the host computer 10 Record the displayed screen. For example, input of specific data (character string) includes reception of screen update request data, reception of screen deletion request data, and the like.

  For example, when it is desired to refer to the screen before the screen update and the current screen at the same time, it is effective when using a host application that automatically changes the screen one after another. Further, the recovery is performed when the host computer 10 unintentionally updates or erases the screen.

  Further, when the timing at which specific data (character string) is received from the host computer 10 is a recording condition, the specific data (character string) is received from the host computer 10 and displayed on the screen of the host terminal 11, Record the screen.

  Here, for specific data, designation such as ““ AAA ”*“ BBB ”” or ““ CCC ”+ EOD” is possible. Here, ““ AAA ”*“ BBB ”” means arbitrary data that starts with “AAA” and ends with “BBB” (for example, “AAAXXXBBB”, “AAABBBB”). ““ CCC ”+ EOD” means “CCC” to the end of one or more continuous data (eg, “CCC1234”). For example, when it is desired to automatically record the contents of the “product list” on the screen of FIG. 9, ““ product list ”+“ user ”” is designated as specific data. FIG. 9 is an image diagram of an example of the screen.

  When a certain time interval is the recording condition, the screen is recorded at a certain time interval set by the operator. In order to avoid recording when the screen is incomplete, if data reception from the host computer 10 continues, screen recording is delayed until the data reception is completed.

  For example, it is effective when you use a host application that periodically changes the screen one after another, but you want to record each screen even if the conditions for screen transition are various or the conditions cannot be specified. is there.

  If the recording timing is the timing at which a certain amount of data is received, a certain amount of data (or the number of characters) set by the operator is received, and the screen is recorded at the timing displayed on the host terminal 11. In order to avoid recording when the screen is incomplete, if data reception from the host computer 10 continues, screen recording is delayed until the data reception is completed.

  For example, it is effective when you use a host application that changes screens one after another irregularly, but you want to record each screen even if there are various screen transition conditions or the conditions cannot be specified. is there.

  If the recording timing is the timing at which the logical session with the host computer 10 is disconnected, the screen displayed immediately before the disconnection is recorded at the timing at which the logical session with the host computer 10 is disconnected. For example, the recovery is performed when an unexpected logical session disconnection occurs due to an operator malfunction, a host application failure, or the like, and data or the like being input is lost.

  When the line disconnection timing is the recording condition, the screen displayed immediately before the disconnection is recorded at the timing when the line between the host computer 10 and the host terminal 11 is disconnected. For example, recovery is possible when input data is unexpectedly lost due to line failure, software malfunction, user's misoperation, and the like.

  Automatic deletion of screen recording data automatically records continuous identical screens when automatic screen recording is performed. Is to be deleted. Automatic deletion of screen automatic recording data is performed, for example, according to the procedure of the flowchart shown in FIG.

  FIG. 10 is a flowchart showing a procedure for automatic deletion of screen automatic recording data. In step S41, the recording control function 61 records the screen A. In step S42, the recording control function 61 records the screen B. Note that the screens A and B are data recorded continuously.

  In step S43, the recording control function 61 determines whether the contents of the screens A and B are the same. If the contents of the screens A and B are not the same, the recording control function 61 ends the process. If the contents of the screens A and B are the same, the recording control function 61 proceeds to step S44, deletes the useless screen B, and ends the process.

  Referencing the screen content refers to the content of the recorded screen (image data, text data). The recorded screen is stored in the recording device 45 of the host terminal 11. When the [List Display] button (icon) on the host terminal 11 is clicked, a specific key is operated, or [Sequential Display] is selected from the menu, a screen data list window is displayed and a list of stored screens Is displayed. The details of the screen data list window will be described later. In this list, the operator selects a saved screen and refers to the contents.

  The display of the screen is to display the screen stored in the recording device 45 in both the image data and text data formats on the display device 44. When a screen is selected in the screen data list window, the contents of the screen are displayed (contents view) with a unique viewer. The content view can specify whether a plurality of screens are displayed simultaneously (a plurality of windows are displayed) or one window is switched.

  FIG. 11 is an image diagram showing an example of screen display. For example, when the screen 80 to be referred to later is displayed on the host terminal 11, the operator records the image data 82 or text data 83 of the screen. When one screen is selected in the screen data list window 81, the image data 82 and the text data 83 on the screen are displayed (contents view) with a unique viewer.

  FIG. 12 is an image diagram of an example of the screen data list window. The screen data list window 90 displays a list of screens (hereinafter referred to as recording data) recorded in the recording device 45 of the host terminal 11. The screen data list window 90 can narrow down and sort the recording data to be displayed, and can easily find the recording data that the operator wants to refer to.

  The display change icon (the icon at the upper left of the window), which is a component of the screen data list window 90, switches the list display format to a detailed list format, a large / small icon format of screen memo history, or a list format.

  In the search field, which is a component of the screen data list window 90, a character string is entered, and a list of recording data including the character string can be listed. Regular expressions can be used for character strings. It also has a string autocomplete function.

  The date and time designation field, which is a component of the screen data list window 90, designates a time range in which recorded data is recorded, and a list of recorded data recorded within the designated time range can be listed.

  When a reset button, which is a component of the screen data list window 90, is clicked, the narrowing conditions in the search field and date / time designation field are reset, and all recorded data is displayed in the list.

  The screen memo history, which is a component of the screen data list window 90, displays a screen of recorded data in a reduced size. When the screen of the recorded data displayed in a reduced size is clicked, the contents of the recorded data are displayed in another window. As an operation at the time of clicking, any one of “display only image data”, “display only text data”, and “display both” can be set in advance.

  The creation date, which is a component of the screen data list window 90, displays the time when the recorded data was recorded. The list can be sorted in descending or ascending order using the creation date as a key.

  The procedure which is a component of the screen data list window 90 displays the timing at which the recording data is recorded. The displayed contents are manual, automatic (key input), automatic (receive 1), automatic (receive 2), automatic (time), automatic (data amount), automatic (logical disconnect), automatic (physical disconnect). . Using this item as a key, the list can be sorted by timing type.

  Manual indicates that the operator manually recorded. Automatic (key input) indicates that recording is performed at “timing when the operator of the host terminal 11 inputs a specific key or specific data” of the automatic recording function. Automatic (reception 1) indicates that recording is performed at “timing when specific data (character string) is received from the host computer 10” of the automatic recording function. Automatic (reception 2) indicates that recording is performed at “timing when specific data (character string) is received from the host computer 10 and displayed on the screen of the host terminal 11” of the automatic recording function. Automatic (time) indicates that recording was performed at a “certain time interval” of the automatic recording function.

  Automatic (data amount) indicates that recording is performed at “timing when a certain amount of data is received” of the automatic recording function. Automatic (logical disconnection) indicates that recording was performed at “timing when the logical session with the host computer 10 was disconnected” of the automatic recording function. Automatic (physical disconnection) indicates that recording was performed at the “line disconnection timing” of the automatic recording function.

  The protection that is a constituent element of the screen data list window 90 indicates whether the recording data is left in the recording device 45 or deleted when the host terminal emulator 51 is terminated. The displayed content is “Yes” or “No”. The list can be sorted using this item as a key.

  The content “YES” displayed in the protection indicates that the corresponding recorded data is not deleted when the host terminal emulator 51 is terminated. Further, the content “NO” displayed in the protection indicates that the corresponding recorded data is deleted when the host terminal emulator 51 is terminated.

  When the delete button, which is a component of the screen data list window 90, is clicked, the corresponding recorded data is immediately deleted from the recording device 45.

  Note that the recording data recorded in the recording device 45 can be continuously displayed, that is, reproduced in chronological order (recording order). Reproduction is performed based on the recording time added to the recorded data. As the reproduction method, either “regular time interval reproduction” or “real time reproduction” can be selected.

  In the case of playback at regular time intervals, an interval (such as 1 second) can be specified. In any of the playback methods, playback, fast forward, rewind, slow, double speed playback, etc. that are equipped with a general VTR, DVD player, etc. can be performed.

  By reproducing the recorded screen data by defining the appropriate automatic recording, only the part that the operator wants to refer to later is collected, that is, control is performed so that a huge amount of data is not collected. Can be confirmed later. In consideration of use for security purposes, the operator of the host terminal 11 uses the automatic recording timing definition set by the administrator of the host terminal 11 and the recording data automatically recorded by the automatic recording definition. It can also have a function to prevent modification / deletion.
