Regarding interactive debuggers that use a terminal device to interactively display and change the contents of variables declared in the user program, display the locus of control, change the flow of control, etc., especially when the user is debugging. This invention relates to an interactive debugger with a memo function that memoizes various matters necessary for debugging as memo data for debugging.

[Conventional technology]

A debugger for debugging a user program executed on a computer system displays the contents of variables declared in the user program.

Debugging is done interactively or in a batch job format, such as changing the contents of variables, tracing the execution order, and changing the execution order.

Traditionally, among this type of debuggers, conversational debuggers include:
The value of a variable at the debugging point set by the user on the user program, the trajectory of control transfer to this debugging point, the address on the main register to which a certain instruction or variable is assigned, and the value of the hardware register. There was no function to store various items required by users such as users during debugging work as memo data for debugging.

[Problem to be solved by the invention]

The conventional conversational debugger mentioned above did not have a function to store memo data for debugging, so the user
While debugging using an RT terminal device, debugging memo data must be written down on prepared paper, and the paper on which debugging memo data is written may be lost. However, the disadvantage is that debugging is inefficient.

In view of the above-mentioned points, an object of the present invention is to enable debugging by simply inputting commands from a CRT terminal device used for debugging work.
You can register memo data for debugging in the debugging buffer memory, display it on a CRT terminal, etc.
The purpose of the present invention is to provide an interactive debugger with a memo function that improves debugging efficiency.

[Means to solve the problem]

The interactive debugger with a memo function of the present invention is an interactive debugger that displays and changes the contents of variables declared in a user program, displays the locus of control, changes the flow of control, etc. registering the memo data in the debugging buffer memory, and displaying the memo data registered in the debugging buffer memory on the CRT terminal device.

A memo function that saves the contents of the debugging buffer memory to a secondary storage device and loads memo data saved in the secondary storage device to the data buffer memory, and a command that executes this memo function. It has a screen splitting function that splits the screen of the CRT terminal device in order to display the execution result and the execution result of the debugging command at the same time.

[Effect]

In the conversational debugger with a memo function of the present invention, the memo function includes registering a debugging memo button in a debugging buffer memory during debugging work, displaying memo data registered in the debugging buffer memory on a CRT terminal device, The contents of the debugging buffer memory are saved to the secondary storage device, the memo data saved in the secondary storage device is loaded to the data buffer memory, and the screen splitting function displays the execution result of the command that executes the memo function. The screen of the CRT terminal device is divided to simultaneously display the execution results of debugging commands.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an interactive debugger with a memo function according to an embodiment of the present invention. The interactive debugger with memo function of this embodiment includes a CRT terminal device 1, a memo data save file 2, and a debugging buffer memory 3.
, a memo buffer memory 4 , a debug function 5 , a memo function 6 , a screen division function 7 , and a debugger control section 8 .

The memo data save file 2 is a permanent file on an external storage device (not shown) that stores memo data registered in the memo buffer memory 4.

The debug buffer memory 3 has a debug function 5 of CR
It is used to exchange data with the T terminal device 1.

The screen splitting function 7 splits the screen of the CRT terminal device 1 so that memo data can be referenced while debugging.

The debugger control unit 8 has a debug function 5. Controls the memo function 6 and screen division function 7.

Referring to FIG. 2, the memo function 6 includes a memo function control section 6.
1, memo function opening means 62, memo data registration means 63, memo data display means 64, memo data saving means 65, memo data loading means 66, and memo function closing means 67.

Next, the operation of the conversational debugger with memo function of this embodiment configured as described above will be explained.

The user starts the interactive debugger with memo function of this embodiment, and when the interactive debugger with memo function is ready to accept debugging commands, sends a command to start the memo function 6 to the CRT terminal device. Insert from 1.

The debugger control unit 8 is controlled by the user from the CRT terminal device 1.
The memo function control section 61 of the memo function 6 is activated by recognizing the command input by the memo function 6 to activate the memo function 6.

The activated memo function control section 61 activates the memo function opening means 62 to put the memo function 6 into a dynamic state and into a state where it can accept memo commands.

When the user inputs a command from the CRT terminal device 1 to register memo data in the memo buffer memory 4, the memo data registration means 63 is activated.

The activated memo data registration means 63 registers the memo data input by the user in the memo buffer memory 4.

The user issues a command to display the memo data registered in the memo buffer memory 4 on the CRT terminal device l.
When inputted from the T terminal device 1, the memo data display means 64
is started. The activated memo data display means 64
If memo data is registered in the memo buffer memory 4, the memo function 6 is terminated by the memo function closing means 67 or other Unless a memo command is executed, the memo data registered in the memo buffer memory 4 is displayed on the CRT terminal device 1.

Similarly to inputting existing debugging commands, when a command to start the screen splitting function 7 is inputted from the CRT terminal device 1, the screen of the CRT terminal device 1 is divided into two by the screen splitting function 7, and each Debug data and memo data are displayed on the screen at the same time.

When the user inputs a command from the CRT terminal device 1 to save the contents of the memo buffer memory 4 to the memo data save file 2, the memo data saving means 65 is activated. The activated memo data saving means 65 saves the contents of the memo buffer memory 4 to the memo data save file 2.

When the user inputs a command to load the memo data stored in the memo data save file 2 into the memo buffer memory 4, the memo data loading means 66 is activated. The activated memo data loading means 66 loads the memo data stored in the memo data save file 2 into the memo buffer memory 4.

The user issues a command to close the memo function 6 on the CRT.
When inputted from the terminal device 1, the memo function closing means 67
is started. The activated memo function closing means 67 terminates the memo function 6.

〔Effect of the invention〕

As explained above, the present invention allows memo data to be displayed on the CRT terminal device at any time during debugging, so that the user can use the same CRT terminal device during debugging to display the memo data as required. Since the memo data can be memorized and easily referred to, there is no need to take notes elsewhere, and the user only needs to keep an eye on the same CRT terminal device, which has the effect of increasing the efficiency of debugging work.
