JPS60132261A - Displaying system of business program symbol name in terminal - Google Patents

Abstract

PURPOSE:To display a business program symbol name on a terminal without making it pass through each business program by containing the business program symbol name in a control command from a computer, and transmitting it, when coupling the business program and the terminal. CONSTITUTION:When a terminal operator inputs a command for requesting a connection to a business program, to a control program, a cession control part 202 derives a business program name of the other party of communication and informs that the connecting request has been executed, to the business program of the other party. Subsequently, the control part 202 generates a control command containing a business program symbol name, and transmits it to a terminal. The terminal analyzes the control command, thereafter, fetches the business program symbol name from a symbol name register 310, and displays the business program symbol name on a display area designated for operator's use 332 of a display picture 331.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a method for identifying the name of a business program connected to a terminal. A method that allows the terminal operator to identify the name of the business program that is connected to the terminal at a certain point in time, even if the name of the business program is changed depending on the terminal.

[Background of the invention]

In the conventional business program identification name display method, a business program connected to a terminal transmits an identification name to the terminal, and the terminal displays the transmitted identification name on a display device. For this reason, it has the disadvantage that it requires a function to transmit the identification name to the terminal for all business programs that may be connected to the terminal.

[Purpose of the invention]

The purpose of the present invention is to display the identification name of the business program connected to the terminal on the terminal, without requiring each business program to have a function of transmitting the identification name to the terminal. be.

[Summary of the invention]

The present invention provides a method for displaying the identification name of a business program to be combined with a terminal, in which the identification of the business program to be combined with the terminal is stored in a control command sent from the system to the terminal when the terminal and the business program are combined. name,
When the terminal receives a control command, it is displayed on the takeout display device.

[Embodiment J of the Invention An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the overall configuration of a computer system and a terminal device as an embodiment of the present invention. 100 is an electronic computer system (hereinafter abbreviated as computer), one of which is
The business program shown in 01 can communicate with any terminal device shown in 104 through a line via the control program 102.

FIG. 2 shows the configuration of the control program.

200 is a control program, 2o1 configuration control, 2
02 session control, 2O3 input/output control and 204
It consists of business program management tables.

Each business program 101 in the computer makes a self-registration request to the control program 102 in advance when starting up the system. FIG. 5 shows a schematic processing flow of the business program registration process on the configuration side a 201. As shown here, when the control program receives a registration request from the business program, it checks the validity of the request as to whether the configuration control in 201 has been defined in the system and whether it has already been registered.
The area of the business program management table shown at 204 is secured, and the identification name of the business program is entered in the entry shown at 214 of this table.

A management table should be created for each business program. After the system has started up in this way, when the terminal operator selects a specific business program in the computer system and attempts to communicate with it, the terminal operator requests the control program to connect with the business program. Submit the requested command. The session control unit 202 executes control for this. A schematic flow of this process is shown in FIG. When receiving a connection command from a terminal, session control unit 2
02 interprets this command based on the name of the business program of the communication partner, and notifies the business program 101 of the other party that there is a connection request.

If the business program 101 can communicate with the terminal,
In order to communicate with the terminal, a request is made to the control program 102 to open a session with the terminal.

When a request to open a session with a terminal is received from the business program, the session control 202 in the control program
After checking the validity of the request as shown in the figure, a control command (BINI command) having the format shown in FIG. 4 is created. First, a frame for the BIND command is created, and information such as the destination terminal address 402 and session parameters is set. Next, the business program identification name 403 is set to the business program identification name 406 of the BIND command in the business program management table 204 of FIG. 2 corresponding to the business program. After this, input/output control 203-'
4, the BINI) command is sent to the terminal.

Next, FIG. 6 shows details of the terminal control device 106 of FIG. 1.

When the BINI) command is sent to the terminal, the line control unit 302 in the terminal control device shown in FIG.

In the case of a BIND command, the HNA command processing unit 605 passes this command to the BIND command processing unit 30B. FIG. 7 shows a schematic processing flow of the BIND command processing section. The BIND command processing unit 506 analyzes the contents of the command, checks the terminal address, checks whether a session has been set, and then checks the session parameters in the BIND command. If the parameters are OK, obtain the business program identification name from the BIND command.

On the other hand, the identification name register corresponds to the terminal device number! +10
is provided. The address of this identification name register 310 is set from the terminal address in the BIND command, and the identification name is set in the register 10. Then, it creates a response and makes a request to send the response as a session setting state.

When the analysis of the BIND command is completed, the display processing unit 608 for the operator in FIG. Set it in the built-in buffer (not shown). Next, the operator sets the on-screen address of the display area in the buffer and requests the display device input/output unit 609 to transfer the buffer to the terminal device Wt104. The terminal device 103 displays the contents of the buffer in the display area 332 of the display screen 331 for the operator. If the instruction is from the UNBIND command processing unit, a space identification name, ie, a blank, is set in the register, and therefore nothing is displayed in the display area 362 for the operator. For the above-mentioned operator, a schematic processing flow of the display processing section 508 is shown in FIG.

When the connection between the business program and the terminal is released, a UN131ND command is sent to the terminal from the control program within the computer. [The JNBIND command is received by the line control unit 302 shown in FIG. 3, and is passed to the UNf3INL) command processing unit 307 via the HNA command processing tfl105.

UNBINL) The command processing unit 307 erases the contents of the identification name register 310 of the relevant terminal. UNBIND
When the analysis of the command is completed, the operator display processing unit 308 saves the identification name in the space to a buffer in order to erase the business program identification name displayed in the display area 362 on the display screen of the terminal device. and transfers the buffer to the terminal device via the display device input/output unit 309.

〔Effect of the invention〕

Conventionally, all business programs communicating with a terminal had to have a function to send their own identification name to the terminal, but according to the present invention, the identification name of the business program communicating with the terminal can be displayed individually. Since this is realized by a control program and a terminal control device without using other business programs, it is easy to develop individual business programs. Also, in cases such as when individual business programs terminate abnormally,
Since no business program is involved, correct information will be displayed on the terminal device.

Additionally, the business program identification name can be displayed for the terminal operator in a display area that is protected from access by individual business programs, such as the display area, increasing security.
