Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal control method for a conversational debugger, and more particularly to a terminal control method for a conversational debugger that automatically generates a support task dedicated to the debugger.

[0002]

2. Description of the Related Art In a conventional interactive debugger terminal control system, as shown in the block diagram of FIG. 2, an interactive debugger 11 on a POS terminal has the same P
It was supposed to run on the OS terminal. In this operation, after starting the interactive debugger 11 and the user program 12, the interactive debugger 11 waits for a command input, and the user program 2 is in a suspended state.
Here, when the user requests execution of the user program 12 by inputting a command from the conversational debugger 11, control is transferred to the user program 12 and executed. After the instruction is completed, the user program 12 is suspended, the termination result is notified to the conversational debugger 11, the control is transferred to the conversational debugger 11, the output information is output to the customer display device or the printer device, and the command is issued again. Wait for input. In this way, layout display, message display, data display, etc. on POS terminals not equipped with a CRT device are
Output was made to a printer device (journal printer or receipt printer) or a customer display device.

[0003]

The conventional terminal control method of the conversational debugger described above does not include a CRT device for output such as layout display, message display, data display, etc., so that the printer installed in the POS terminal Since the data is output to the device (journal printer or receipt printer) or the customer display device, there are problems such as slow display speed, small number of display digits, and difficulty in seeing user program output and debugger output mixed. In addition, the quick response that is a feature of the conversational debugger and the display of rich debug information such as the source program display of the user program cannot be displayed, which is a constraint to fully demonstrate the functions of the conversational debugger. There are also points.

The object of the present invention is to promptly display debug information such as layout, messages, data and source programs of user programs on a CRT device of a workstation connected to the same terminal controller. It is to provide a terminal control method of an interactive debugger that can facilitate debugging work by a person.

[0005]

The terminal control method of the interactive debugger according to the present invention is the debugging of the user program by the interactive debugger on the POS terminal, which is performed on the workstation connected to the same terminal controller. I / O processing dedicated interactive debugger that operates in
A conversational debugger dedicated to internal processing that operates on a terminal is separated, and a support task dedicated to the debugger that connects the conversational debugger dedicated to input / output processing and the conversational debugger dedicated to internal processing is automatically generated on the terminal controller. is there.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.

In FIG. 1, 1 is a user program that is actually operated, 2 is a conversational debugger dedicated to internal processing, which is operated by an instruction from a dedicated support task 4 and also includes an internal control function for the user program 1, and 3 is a work. Interactive debugger dedicated to input / output processing including input control for user command input and output of debug information automatically generated on a station (hereinafter referred to as WS terminal), 4 is on a terminal controller (hereinafter referred to as TC) Dedicated support tasks including command analysis and output control of debug information of the I / O processing dedicated conversational debugger 3 and control of the internal processing dedicated conversational debugger 2 are performed from the I / O processing dedicated conversational debugger 3 to the dedicated support task 4. 6 represents a command control transfer, and 6 is a dedicated internal processing group waiting for an instruction from the dedicated support task 4. Represents the transfer of control to the type debugger 2, 7 represents the transfer of execution from the internal processing dedicated conversational debugger 2 to the user program 1, and 8 represents the internal processing dedicated conversational debugger after the instruction to the user program 1 is completed. Two
9 represents the transfer of control to the dedicated support task 4, and 9 represents the transfer of control from the conversational debugger 2 for internal processing to the dedicated support task 4.
Reference numeral 10 represents a transfer of control from the dedicated support task 4 to the input / output processing dedicated interactive debugger 3 after the command is completed.

Next, the operation will be described.

The interactive debugger 3 dedicated to input / output is activated on the WS terminal, and the interactive debugger 2 dedicated to internal processing is activated on the POS terminal. At this time, the dedicated support task 4 is automatically generated on the TC immediately after the activation of the input / output dedicated conversational debugger 3. Next, the user program is activated by another task on the POS terminal, and the user program is suspended by a preset interrupt command. The user
When a user program execution request is made by keyboard input of the input / output dedicated conversational debugger 3, the input / output dedicated conversational debugger 3 transfers command control to the dedicated support task 4, and the dedicated support task 4 executes the command After the analysis, the control is transferred to the internal exclusive conversational debugger 2 waiting for the instruction, and the user program 1 is executed. After the instruction to the user program is completed, the internal dedicated conversational debugger 2 receives the input / output dedicated conversational debugger 3 via the dedicated support task 4.
The control is transferred to, and the user waits for a command input again. The dedicated support task 4 is automatically deleted when the input / output dedicated interactive debugger 3 is terminated.

[0011]

As described above, according to the present invention, a conversational debugger dedicated to input / output processing and a PO operating on a workstation connected to the same terminal controller are provided.
By separating the internal processing-dedicated conversational debugger running on the S terminal and automatically generating a debugger-dedicated support task connecting the input / output processing-dedicated conversational debugger and the internal processing-dedicated conversational debugger on the terminal controller,
By displaying the layout, messages, data, and debug information such as the source program of the user program on the CRT device of the workstation promptly, the user's debugging work can be facilitated.
