Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program evaluation device for evaluating a program operating on a computer system such as a slip issuing machine.

[0002]

2. Description of the Related Art When a program is developed using a computer system such as a slip issuing machine, the development work generally includes a program creation work and a program evaluation work.

[0003] Program creation is a task in which a developer inputs a program code from an input device such as a keyboard to create a program. Program evaluation is performed by using a software evaluation tool generally called a debugger. This is the task of executing the program created in the creation work and checking and evaluating the operation.

In such a program evaluation work,
If a defect is found, the program returns to the program creation operation, corrects the program, and performs the program evaluation operation again.

[0005] Then, the program development work and the program evaluation work are repeatedly performed until there is no defect in the program, and then the program development work ends.

In a program evaluation operation, when a program to be developed displays a screen at the time of execution, an evaluation information screen displayed by a debugger and an execution screen displayed by the program at the time of execution are simultaneously displayed on a display unit.

[0007] The evaluation information screen is a screen composed of a display of menus and buttons for the developer to give an instruction to execute an evaluation function, a display of a program code of a program to be evaluated, and the like. The screen displayed on the display unit by the program as a result of an instruction to execute the program created by the user.

[0008]

SUMMARY OF THE INVENTION A program developer
On the evaluation information screen, give instructions such as partial execution of the program,
By checking the execution result on the execution screen, the program was evaluated.

FIG. 6 shows a display example displayed on a conventional program evaluation device.

As shown in FIG. 6, on the screen of the conventional method,
At the time of the evaluation work, the execution screen 1 of the program is displayed in the same size as that of the normal execution, so that the display positions of the execution screen 1 and the evaluation information screen 2 are overlapped.

In order to confirm the display of the portion of the execution screen 1 hidden under the evaluation information screen 2, it is necessary to change the display position of the evaluation information screen 2.

That is, the evaluation information screen 2 is moved up, down, left and right while being positioned in front of the execution screen 1, or the evaluation information screen 2 is temporarily moved to the back of the execution screen 1, After confirmation, it was necessary to move to the front of the execution screen 1 again.

Since such a movement is performed by a developer using an input device such as a keyboard, the number of operations required by the developer increases, and there has been a problem that the work efficiency in program evaluation is reduced.

If the developer forgets or neglects the work of moving the evaluation information screen 2, the program evaluation work ends without confirming the display of the execution screen 1 portion hidden under the evaluation information screen 2. And the quality of the program is degraded.

The present invention has been made in view of the above points, and has as its object to provide a program evaluation device, a computer-readable recording medium, and a slip issuing machine capable of improving the work efficiency in a program evaluation operation. It is in.

[0016]

According to a first aspect of the present invention, there is provided a program evaluation device for displaying and evaluating a program running on a computer system.
Display magnification storage means for storing a display magnification for the execution screen of the program, size change means for reducing or enlarging the size of image data or character image data to be displayed by the program based on the display magnification, and a program execution screen. Display control means for reducing or enlarging based on the display magnification and displaying the image data or character image data reduced or enlarged by the size changing means on a display unit.

Here, the display magnification is a ratio of the execution screen size at the time of the evaluation work based on the execution screen size at the time of normal execution of the program.

For example, when the display magnification is 1, the execution screen at the time of normal execution and at the time of evaluation work have the same size.

When the display magnification is smaller than the value 1, the execution screen at the time of the evaluation work is reduced, and when the display magnification is larger than the value 1, the execution screen at the time of the evaluation work is enlarged.

Therefore, by setting the display magnification to a value smaller than 1 and reducing the size of the execution screen and displaying the evaluation information screen at a position other than the execution screen, the execution screen and the evaluation information screen are displayed simultaneously without overlapping. You can do it.

That is, as shown in FIG. 5, the program execution screen is reduced at the time of normal execution and displayed at the top of the screen, and the evaluation information screen is displayed at the bottom of the screen. And there is no overlap between the two screens.

According to a second aspect of the present invention, the display magnification stored in the display magnification storage means can be changed by an external input.

As described above, since the display magnification can be changed by the external input, the operator can adjust the size of the execution screen to an optimum size.

According to a third aspect of the present invention, when the display magnification storage means stores the display magnification for reducing the execution screen, the evaluation information screen used to instruct the execution of the execution screen and the evaluation function. Are displayed at different positions so that the display unit does not overlap.

As described above, since the execution screen and the evaluation information screen are prevented from overlapping on the display unit, when the execution screen and the evaluation information screen are operated, it is necessary to shift the positions of the execution screen and the evaluation information screen one by one. Because there is no operation efficiency, the operation efficiency can be improved.

That is, the size of the execution screen of the program is changed and displayed according to the display magnification, so that the execution screen and the evaluation information screen can be displayed without overlapping during the program evaluation work. This eliminates the need for the program developer to move the display position of the evaluation information screen when checking the execution screen, and allows evaluation while viewing the entire execution screen, improving program development efficiency and program quality. Can be done.

A program for realizing display control function means for displaying at different positions so as to eliminate the overlap on the display unit is recorded.

According to a fifth aspect of the present invention, there is provided a slip issuing machine for inputting necessary data in a displayed slip format and issuing a slip in the slip issuing machine by setting a display magnification for an execution screen of a program operating on the slip issuing machine. Display magnification storage means for storing, size changing means for reducing or enlarging the size of image data or character image data to be displayed by the program based on the display magnification, and reducing or enlarging the program execution screen based on the display magnification In addition, the image data and the character image data reduced or enlarged by the size changing means are displayed on the display unit, and the execution screen and the evaluation information screen used for the instruction to execute the evaluation function are not overlapped on the display unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a computer system such as a slip issuing machine.

In FIG. 1, reference numeral 11 denotes a CPU (central processing unit) for controlling a computer main body. This CPU1
1, a ROM (Read Only Memory) 12 for storing information for controlling each unit by the CPU 11, and a RAM (Random Access Memory) for storing various information for application programs and data processing. ) 13, an external memory 14 such as a hard disk for storing data, a keyboard interface 16 for controlling data transmission to and from a keyboard 15, a display controller 18 for controlling a display 17, and a storage for a floppy (registered trademark) disk or the like. A storage medium interface 20 for controlling data transmission with the medium 19.

Next, referring to FIG. 2, there is shown a diagram illustrating an embodiment of a program evaluation device according to the present invention. FIG.
In the program evaluation device of the present invention, the CPU 11
It is composed mainly of. The CPU 11 includes a program management unit 23 that manages a program file 34 described later, a step execution unit 24 that executes the program for one step, an input unit 25 that receives a key input from the keyboard 15, and a display magnification. It comprises a size changing means 26 for reducing or enlarging image data and character image data, and a display control means 27 for displaying image data and character image data on the display 17. These program file management means 23 and step execution means 2
4, input means 25, size changing means 26, and display control means 27 are programs stored in the RAM 12 described above.

Here, when the display magnification is smaller than the value 1,
The execution screen during the evaluation work is displayed in a reduced size, and the display magnification is set to a value of 1.
When it is larger, the execution screen at the time of the evaluation work is enlarged and displayed.

Therefore, by setting the display magnification to a value smaller than 1 and displaying the execution screen in a reduced size and displaying the evaluation information screen at a position other than the execution screen, the execution screen and the evaluation information screen are displayed simultaneously without overlapping. You can do it.

That is, as shown in FIG. 5, the program execution screen 1a is displayed in a reduced size from the time of normal execution and displayed at the top of the screen, and the evaluation information screen 2a is displayed at the bottom of the screen.
And there is no overlap between the two screens.

A program file 34 for storing programs, a program buffer 28 for storing programs to be evaluated, and a step number buffer 29 for storing step numbers of programs to be executed are connected to the program management means 23.

The step executing means 24 is connected to a program buffer 28, a step number buffer 29, and a debug information buffer 30 for storing a break point indicating a program execution pause position.

The input means 25 is connected to a debug information buffer 30 and a display magnification buffer 31 for storing the display magnification of the program execution screen.

The size changing means 26 includes a display magnification buffer 31, an image file 35 for storing image data displayed by the program to be evaluated, and image data obtained by reducing or enlarging the image data of the image file based on the display magnification. Buffer 32 for storing character image data displayed by the program to be evaluated, and a font for storing character image data obtained by reducing or enlarging the character image data of the font file based on the display magnification. The buffer 33 is connected.

The display control means 27 reduces or enlarges the image data of the image file based on the display magnification and stores the image buffer 32 storing the image data and the character file of the font file based on the display magnification. A font buffer 33 for storing the subsequent character image data is connected.

Next, the operation of the program evaluation apparatus according to one embodiment of the present invention will be described with reference to the flowcharts of FIGS.

First, in the flowchart of FIG. 3, a buffer initialization process is performed (step S1). That is, in the buffer initialization process, the CPU 11 stores the display magnification for initialization, for example, a value of 0.8 in the display magnification buffer 31. Then, the first step number of the program, for example, the value 1 is stored in the step number buffer 29.
Then, the entire contents of the debug information buffer 30 are erased.

Next, the evaluation information screen is initialized (step S2). In this case, the initial screen of the evaluation information screen is displayed on the display 17 by the display means 27. The display position is, for example, the position shown in 2a of FIG.

That is, based on the display magnification, the display control means 27 controls the display so that the evaluation information screen 2a does not overlap the lower side of the reduced execution screen 1a.

As described above, by displaying the evaluation information screen 2a so as not to overlap the execution screen 1a,
When operating both the execution screen 1a and the evaluation information screen 2a, there is no need to move the execution screen 1a and the evaluation information screen 2a on the screen, so that the efficiency of the evaluation work can be increased.

Next, the input means 25 determines whether or not the operator has made a keyboard input of a request to change the display magnification on the evaluation information screen (step S3).

If the determination in step S3 is "NO", that is, if no change request has been received, the process proceeds to step S5.

On the other hand, if the determination in step S3 is "YES",
That is, when it is determined that the change request input has been received, the input unit 25 stores the display magnification acquired from the keyboard 15 in the display magnification buffer 31 (step S4).

As described above, since the display magnification can be changed from the keyboard 15, the operator can optimally set the size balance of the actually displayed execution screen 1a or evaluation information screen 2a.

Next, as a program file selection, the display control means 27 displays on the display 17 prompting the user to select a program, and the input means 25 acquires the selection result from the keyboard 15 (step S5).

Then, the program management means 23 reads the program file selected in step S5 from the program file 34 and stores it in the program buffer 28 (step S6).

The display control means 27 displays the program in the program buffer 18 in the evaluation information screen 2a from the step indicated by the step number in the step number buffer 21 (step S7).

That is, the step number 2b and the step 2c are displayed in the evaluation information screen 2a. Here, 2d represents the head position of the printer.

Next, the evaluation information screen 2 is
A keyboard input of a function execution request for a is obtained (step S8). Here, the function input is evaluation information screen 2
This is the “function” of the menu a.

Here, it is assumed that functions that receive an execution request include, for example, program reselection, execution initialization, breakpoint setting / cancellation, one-step execution, continuous execution, and termination.

Then, it is determined which function the execution request acquired in step S8 is (step S9).

If it is determined in step S9 that the function is "program reselection", the process proceeds to step S3 described above.

If it is determined in step S9 that the function is "execution initialization", the process proceeds to step S10.

If it is determined in step S9 that the function is "set / cancel breakpoint", step S11 is executed.
The process proceeds to.

If it is determined in step S9 that the function is one-step execution, the process proceeds to step S12.

If it is determined in step S9 that the function is "continuous execution", the process proceeds to step S13.

"The function ends" in the judgment of step S9
If so, the process proceeds to step S15.

In step S10, the CPU 11 performs processing for storing the start step number of the program in the step number buffer 29. Thus, the execution of the program is performed from the first step.

When the process in step S10 is completed, the process returns to step S7.

In step S11, the input of setting or canceling of a step number as a break point is obtained by the input means 25.

Here, in the case of a breakpoint setting input, the input step number is stored in the debug information buffer 30.

On the other hand, in the case of a breakpoint release input, the step number to be released is deleted from the debug information buffer 30. When the process in step S11 ends, the process proceeds to step S7.

Next, one-step execution processing is performed (step S12). This one-step execution process will be described later with reference to the flowchart of FIG. When the process in step S12 ends, the process proceeds to step S7.

In step S13, one-step execution processing is performed. The one-step execution process is the same as step S12, and will be described later with reference to the flowchart of FIG.

Next, the CPU 11 stores the step number of the step number buffer 29 in the debug information buffer 3.
It is checked whether or not there is a breakpoint of 0 (step S14).

If the determination in step S14 is "YES",
In other words, if it is determined that there is, the process proceeds to step S7. On the other hand, if “NO” in the determination in step S14, that is, if it is determined that the file does not exist, the process proceeds to step S13.

Next, the display of the evaluation information screen 2a is deleted by the display control means 27 (step S15).

Then, by the end of step S15, a series of operations by the program evaluation device ends.

Next, referring to the flowchart of FIG.
The step execution processing (step S12) will be described in detail.

First, it is determined whether the execution has been completed (step S21). In determining whether or not the execution has been completed, the step execution means 24 checks the contents of the step number buffer 29 and determines whether or not the value indicates the completion of the execution, for example, the value -1.

If the determination in step S21 is "YES", the one-step execution process ends.

On the other hand, if "NO" is determined in the determination in step S21, that is, if the value is not a value indicating the end of execution, the process proceeds to step S22.

In step S22, the program code of the step indicated by the step number in the step number buffer 29 is read from the program buffer 28 by the step executing means 24.

Here, it is assumed that the program code for one step is composed of one or more commands, and execution of a step means that these commands are sequentially executed from the head.

Then, the step executing means 24 determines the type of the command to be executed (step S2).
3).

If it is determined in step S23 that "the type of command is an image display command", the process proceeds to step S24, and it is determined that "the type of command is a character display command". In this case, the process proceeds to step S28, and when it is determined that the command type is a command other than the display command, the process proceeds to step S32.

First, with reference to steps S24 to S27, the processing when it is determined that the command type is an image display command will be described.

First, the size changing means 26 reads out image data from the image file 35 (step S24).

Then, the size changing means 26 changes the size of the read image data according to the display magnification of the display magnification buffer 31 and stores it in the image buffer 32 (step S25).

Then, the size changing means 26 multiplies the display coordinates specified by the parameter of the image display command by the display magnification, and calculates the coordinates for displaying the image data after the size change (step S26).

Further, the display control means 17 displays the image data of the image buffer 32 from the calculated coordinate position (step S27).

Next, the execution processing of the character display command will be described with reference to steps S28 to S31.

First, the size changing means 26 reads out character image data from the font file 26 (step S2).
8).

The size of the read character image data is changed according to the display magnification of the display magnification buffer 31 and stored in the font buffer 33 (step S2).
9).

The size changing means 26 multiplies the display coordinates specified by the parameter of the character display command by the display magnification, and calculates the coordinates for displaying the character image data after the size change (step S30).

Then, the display control means 27 displays the character image data in the font buffer 33 from the calculated coordinate position (step S31).

Next, a process for executing a command other than the display command will be described with reference to step S32. Here, the commands other than the display command include, for example, numerical calculation commands, keyboard input commands, and the like.

Then, steps S27, S31, S32
Is completed, it is determined whether the execution of the last command has been completed (step S33).

If the determination in step S33 is "NO", the processing from step S23 described above is repeatedly executed.

On the other hand, in the determination of step S33, “YE
If it is determined to be "S", the step number to be executed next is stored in the step number buffer 29. When the program execution is completed and there is no next step to execute, a value indicating the end of the execution, for example, the value -1 is stored.

Then, upon completion of step S34, 1
The step execution processing ends.

As described above, since the size of the program execution screen 1a is changed and displayed according to the display magnification, the execution screen 1a and the evaluation information screen 2a can be displayed without overlapping during the program evaluation work. Become.

Therefore, when the program developer checks the execution screen, the trouble of moving the display position of the evaluation information screen 2a can be omitted and the evaluation can be performed while viewing the entire execution screen 1a. Program quality can be improved.

A size changing function means for reducing or enlarging the size of image data or character image data to be displayed by the program based on the display magnification, and reducing or enlarging the program execution screen based on the display magnification. The image data or character image data reduced or enlarged by the size changing means is displayed on the display unit, and the execution screen and the evaluation information screen used for the instruction to execute the evaluation function are located at different positions so that the display unit does not overlap. A program for realizing the display control function means for displaying on the storage medium 19 is stored in a recording medium 19 such as a floppy disk, and the program is read by a computer system as shown in FIG. Similar effects can be obtained.

According to the first aspect of the present invention, since the execution screen can be reduced or enlarged, both the execution screen and the evaluation information screen can be displayed on the display unit. Work efficiency can be improved.

According to the second aspect of the invention, since the display magnification can be changed, the operator can optimally set the size balance of the actually displayed execution screen or evaluation information screen.

According to the third aspect of the present invention, the execution screen and the evaluation information screen are prevented from overlapping each other on the display unit. Therefore, when the execution screen and the evaluation information screen are operated, the execution screen and the evaluation information screen are operated. It is not necessary to shift the position of each item, so that the operation efficiency can be improved.

That is, since the size of the execution screen of the program is changed and displayed according to the display magnification, the execution screen and the evaluation information screen can be displayed without overlapping during the program evaluation work. This eliminates the need for the program developer to move the display position of the evaluation information screen when checking the execution screen, and allows evaluation while viewing the entire execution screen, improving program development efficiency and program quality.
