Abstract

PURPOSE:To make an input file and an output file the same and to prevent the confusion of the files by providing an editing file in the generation and updating processing of a program having plural screen control programs. CONSTITUTION:A program generator 6 reads the program to be updated from the input file 1 and is edited as the permutation of the screen control programs being the display unit of a screen 4, and written into the editing file 3 at the updating time of the program. The initial screen control program in the editing file 3 is then read by the program generator 6 into a program buffer 7, displayed in the screen 4, and the object of a processing comes to the content of the editing file 3. When the content displayed in the screen 4 needs correction, an operator inputs correction information from a keyboard 5 and corrects the content on the screen 4. Thus, the confusion of the input and output files can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for generating and updating a program spanning multiple screens during display in a program generator that directly outputs a load module for an interpreter.

(Prior art) Conventionally, this type of program generator generates a program by directly outputting the content edited on the screen to a file, and also displays the content read from the file on the screen and displays it. The program was updated by updating and outputting directly to a file.

Therefore, in order to update a program that spans multiple screens during display, it is necessary to repeat reading, updating, and outputting for each screen.

(Problems to be Solved by the Invention) In the conventional program generator described above, the contents updated on the screen are directly output to the load module file, so there are the following problems.

(1) Since the input file and the output file must be separated, there is a risk that it will become impossible to identify which file is the latest file after multiple updates.

(2) The generated or updated content is directly output to a file when the program for one screen display (screen control program) is completed, so when the generation or update of one screen control program is completed, Unable to update previous screen control program.

(3) The updated contents are output directly to the file, so
In order to update a program that has multiple screen control programs, it is necessary to update the program in order starting from the first screen control program, so it takes time to find the desired part.

(4) While one program is being generated or updated, other programs cannot be referenced.

(Means for Solving the Problems) A program update method provided by the present invention in order to solve the above-mentioned problems is a program update method in a generator that directly handles load modules, and includes an output file that stores an updated program. an input file that stores the program to be updated, an edit file that stores the program to be updated stored in this input file edited into the permutation of the screen control program that is the screen display unit, and the above that is the update target. Input a program buffer that holds the screen control program, a screen that displays the screen control program held in this program buffer, and the content to update the screen control program displayed on this screen, and update the screen control program after the update. The present invention is characterized by comprising a keyboard for issuing an instruction to output a screen control program from the program buffer to the output file.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a program update method according to an embodiment of the present invention.

In the figure, 1 is an input file, 2 is an output file, 3 is an edit file, 4 is a screen, 5 is a keyboard, 6 is a program generator, and 7 is a program buffer.

When updating a program, the program to be updated is read from the input file 1 by the program generator 6, edited as a sequence of screen control programs that are display units of the screen 4, and written to the editing file 3. Thereafter, the first screen control program of the edit file 3 is read into the program buffer 7 by the program generator 6 and displayed on the screen 4. Thereafter, the contents of the edit file 3 will be processed. When the operator needs to modify the content displayed on the screen 4, the operator inputs modification information from the keyboard 5 to modify the content on the screen 4.

In addition, if it is necessary to update another screen control program, by specifying the target screen number from the keyboard 5, the screen control program corresponding to the specified screen number is stored in the program buffer 7 from the edit file 3. It is read and displayed on screen 4. When the operator wants to update the program with the contents modified on screen 4, by pressing a specific key on keyboard 5, the screen control program currently displayed on screen 4 will be updated to the corresponding one in edit file 3. written in the section.

Next, # of mgk file 3! The flow is shown in Figure 2.

The program header section is 0 screen control glodarum #O, #1.copied from input file 1. ....

#n has a fixed size and guarantees the largest screen control program that can be generated. Each screen control program read from the input file 1 is copied to the position of the corresponding screen control program #O, #1°, . . . , #n in the editing file 3.

In this way, since the contents of edit file 3 are in a different format than the load module file, the operator must -
At the time of program generation or program update, an operation is performed to output to the output file 2 in order to create a load module format.

At this time, output file 2 may be the same as input file 1.

Furthermore, if it is desired to refer to another program, a specific screen control program of that program can be read into the position of an arbitrary screen control program in the editing file 3.

(Effects of the Invention) As described above, the present invention provides the following effects by providing an edit file in the generation and update processing of a program having a plurality of screen control programs.

(1) Since the input file and output file can be the same, file confusion can be prevented.

(2) Other screen control programs within the same program can be referenced arbitrarily.

(3) It becomes possible to directly designate and update a specific screen control program within a program.

(4) fl! It becomes possible to refer to a specific screen control program of the I program.

Claims (1)

[Claims] In a program update method in a generator that handles direct load modules, an output file that stores an updated program, an input file that stores a program to be updated, and the program to be updated that is stored in this input file. an edit file that edits and stores the screen control program in the permutation of the screen display unit, a program buffer that holds the screen control program to be updated, and displays the screen control program held in this program buffer. and a keyboard for inputting contents to update the screen control program displayed on this screen and for instructing to output the updated screen control program from the program buffer to the output file.
