Abstract

PURPOSE:To make correction of a source program easy by displaying a layout image of a picture defining section in a picture display unit, correcting the display by inputting of interactive system observing the display, and correcting the source program automatically. CONSTITUTION:A source program 7 is converted to intermediate codes by a program analyzing means 8. When executing, an image displaying means 10 displays a layout image of a picture defining section or a document defining section of the display picture of a picture display unit 5. An operator changes the intermediate codes observing the display. The changed image is displayed in the display picture, and this changing operation is repeated until judgement becomes OK. Thus, the intermediate codes changed by a file forming means 12 of the intermediate codes are stored as intermediate codes 9 and converted to a source program 14 by a source program forming means 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for modifying a source program, and particularly to a method for modifying a source program including a screen definition section or a ledger definition section.

[Conventional technology]

l! Figure 3 is a block diagram showing a computer system used for modifying source programs, in which 11) is a processing unit, (2) is a control unit, (3) is a main storage unit, and (4) is a processing unit.
is a disk device as an auxiliary storage device, (5) is a screen display device, and (6) is a keyboard device.

FIG. 4 is a flowchart showing the conventional method, (40)
-(48) indicate each step. It is assumed that the source program to be modified is stored as a file in the disk device (4), and in step (41) the source program is stored in the main storage device (3).
and modified by the source editor in step (42). Source editors include line source editors and screen source editors.In the case of the line source editor, one line of the source program is created as a source program, and in the case of the Sfreece source editor, multiple parts of the source program are created simultaneously. is displayed on the screen display device (5) in the form of , and the operator makes an interactive correction to the source program. Modifications to the table definition section cannot be executed in step (42), so step (
44) and (45), then step (46) (
Execution test image confirmation) (2) Therefore, the image of the screen layout is displayed on the screen display device (5), the operator confirms it, and if the judgment in step (47) is NO, the process returns to step (41), and the process returns to step (41). After making the necessary modifications in step (42), the modified source program (step (43)) can be used to create step-by-step programs (45) and (4).
6), (47) need to be repeated, and step (4)
Since the confirmation in step 6) and the correction in step (42) are only indirectly related, the time and effort required for the correction increases.

[Problem that the invention seeks to solve]

As described above, when a source program includes a screen definition section or a ledger definition section, the source program regarding these definition sections is modified indirectly using conventional methods, so it can be done accurately and in a short period of time. There was a problem in that it was difficult to carry out necessary modifications.

This invention was made to solve the above-mentioned problems, and the source programs of the screen definition section and @table definition section can also be input interactively through the display on the screen display device (5). The purpose is to obtain a source program modification method that allows direct modification.

[Means for solving problems]

In this invention, the screen definition part and the ledger definition part of the source program are replaced with intermediate code (2) from the programming language used in the source program, and this intermediate code; While observing this image, the user modifies this image using input using interactive C2, and automatically modifies that part of the source program via intermediate code.

[Effect]

In the method of the present invention, the layout image of the screen definition section is displayed on the screen display device (2), and the source program can be automatically modified by modifying this display through interactive input while observing this display. Source programs can be easily modified.

〔Example〕

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

FIG. 1 is a block diagram showing one embodiment of the present invention.
3, the same reference numerals as in FIG. 3 indicate the same or corresponding parts, and FIG. 1 shows the functional parts when the apparatus shown in FIG.

In FIG. 1, (7) is the source program stored in the source program file, (81 is the source program analysis means, (9) is the intermediate code, (1 is the runtime image display means, and (12) is the intermediate code. code file generation means, (13) source program generation means, (14)
) is the modified source program.

Further, FIG. 2 is a flowchart showing the operation of the apparatus shown in FIG. 1C, and (20) to (27) are each step. FIG. 5 is a perspective view showing the execution image displayed on the screen display device (5) in FIG. 1, in which the same reference numerals as in FIG. screen, (16) is a parameter for modifying the screen layout, (
17) is a field definition character that distinguishes parameter fields.

Next, the present invention will be explained in detail using FIG. 2.

Step (21) From l2, the source program (7) from the source program file is input to the main storage device (3). This source program (7) is converted into intermediate code by a source program analysis means (8).

That is, the intermediate code of the screen definition section, the intermediate code of the ledger definition section, the intermediate code of the file definition section, and the intermediate code of the procedure section of the source program are generated from the source program, and the intermediate code file shown in step (22) is generated. This process results in an intermediate code (9). The runtime image display means (10) uses the intermediate code (9) under program control in the processing device (1) to display the screen definition section or A layout image of the ledger definition section is displayed, for example, as shown in FIG. 5 (step (23)). If the operator who has observed this display (step (24)) gives OK in the determination in step (25), the process moves to step (26). In this case, the intermediate code file in step (26) will be the same as that in step (22), so the source program input (step (21)) will be the same as the source program generation (27) in step (27).
This is stored as a source program after 1i.

If the determination in step (25) is No, change the intermediate code while observing the display on the return display screen (15) between steps (22) and (23). This is done by moving a cursor (not shown in FIG. 5) and inputting screen layout parameters (16) and parameter field definition characters (17) using a keyboard device (6). This change changes the contents of the intermediate code file, and the image changed by the change is displayed on the display screen (15). Immediately after, this change operation is continued until the judgment of Stella 7' (25) is OK. repeat. In this way, the intermediate code modified by the intermediate code file generation means (12) is stored as an intermediate code (9), and then the source program generation means (13) converts the intermediate code (9) into a source program ( 14) and stored as a source program file.

〔Effect of the invention〕

As described above, according to the present invention, when modifying a source program including a screen definition section or a ledger definition section, the execution images of the screen layout and the ledger layout are displayed on the screen display device and the images are checked while the correction is made. This eliminates the need for a series of confirmation tasks such as compilation, load module production test execution, and layout confirmation as in the conventional method, and it is possible to quickly modify the source program.
