Description

[Detailed description of the invention] [Industrial application field] The present invention relates to computer systems.

This field relates to translation programs such as assemblers, and particularly to output methods for program errors.

[Prior art] Combita dero dalam (hereinafter referred to as
The source program is translated into machine language (hereinafter referred to as an ectoderogram) using a translation program such as a computer programmer or an assembler before being executed.

Traditionally, language and syntax errors are discovered when translating a source program into an object program using this type of translation program.

Source image as Con/Mother Illist,! : -Printed together.

[Problems to be Solved by the Invention] However, in the conventional program error output method described above, the presence or absence of an error and the location of the error are not known until the compile list is output. I was unable to do the work to correct it, which was a waste of time. Furthermore, even if the control list is output, the source program must be modified using a screen editor while comparing both the screen and the control list, resulting in poor work efficiency. Furthermore, in some cases, a huge amount of compile list is output in order to correct a small error, which is a problem in terms of resources.

The present invention solves these conventional problems.
To provide a program error output method capable of displaying the error state on the screen together with an image of the source program line in which the error has occurred.

[! Means for Solving Problem 1] In order to achieve the above object, the present invention provides an error state output means for detecting and outputting an error in a source program, and an error state holding means for retaining the output error state. In a translation program having a file, error state addition output means for outputting an error state held in the error state holding file and a source image of a source program in which this error state is found in association with each other;
A program error output method is provided that includes an output subfile for storing the output of this error state additional output means.

[Function] Therefore, according to the present invention, the error state held in the error state holding file is stored in the output subfile in association with the source image of the source program by the error state additional output means, so that the error state is stored in the output subfile in association with the source image of the source program. The output subfile can be displayed on the screen upon request, and the programmer can correct errors in the source program without looking at the computer's file list.

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the 7'a-gram error output method of the present invention.

In Figure 1, 1 is a source program library;
It is composed of an input subfile 11 and an output subfile 12. The input subfile 11 stores a source program A consisting of m records from record A1 to record Am. Each record consists of a line number and a source image, and record Ai (1≦
The line number of l≦1) is expressed as All, and the north image of record A1 is expressed as A21.

Output subfile 12 is from record B1 to record B1
It consists of up to 11 n@ records and stores source images or error conditions as described below.

Each record consists of a line number and a source image or error state (“source image/error state” in the figure means the source image or error state), and the record B (l≦j≦n). The line number is represented by Blj, and the source image or error status of record J is represented by BJQ.

With the 2Fi compiler, compile means 21, -'-,
'-Consists of status output means 22 and error status additional output means 23. The computer/main file means 21 outputs the object program converted by the source program AI in the input subfile 11 to the object library 3, and outputs the contour list to the report file 4. The error state output means 22 outputs the line number and error state of the source 7'ogram A in which the error has been detected to the error state holding file 5. The error state addition/output means 23 operates to store the error state held in the error state holding file 5 and the source image of the input subfile 11 in the output subfile 12 in association with each other based on their respective line numbers. do.

3 is an object library that stores compiled object programs, and 4 is a report file that stores a contour list.

Reference numeral 5 denotes an error status holding file composed of p records from record C1 to record Cp. The record ck (1≦ and ≦p) consists of a line number C1k holding the line number A11 (1616m) of the source program A where the error condition C2k was found, and an error condition 02k.

Enter the second figure! File 11, error status retention file 5. 3 is a diagram showing a specific example of records of the output subfile 12. FIG. The figure (&) shows an input subfile 11 consisting of ten records from record A1 to record A10t. The row numbers All to All0K are given numbers from 0010 to 0100, and the source images corresponding to the respective row numbers are shown in A21 to A210.

In the same figure (b), records C1 and C representing two error states are shown.
This is an error status holding file 5 consisting of 2. Record CI is source image A2 of line number A17 of human subfile 11 that matches line number C11O value 0070
This indicates that the error state related to 7 is C21. Similarly, the value of record C2F1 line number C12 is 00
80 indicates that the error status regarding source image A28 of line number A18 of input subfile 11 is C22.

FIG. 2C shows an output subfile 12 created from the input subfile 11 and the error status holding file 5, and is composed of 12 records from record B1 to record B12. The method for creating the output subfile 12 by the error state addition output means 23 will be described below with reference to the flowchart in FIG.

The functions and operations of the controller 21 and the error status output means 22 of the controller 2 are well known. Assume now that the error status holding file 5 shown in FIG. 2(b) is obtained as a result of the configuration file. The error state addition/output means 23 reads the first record C1 from the error state holding file 5 (step 231), learns from the line number C11O value that the first error has occurred at line number value 0070, and converts it to the input subfile. 11, records A1 to A71 from line number All to line number A17t are copied from record B1 to record B7 of output subfile 12 (Stella 7''232).

Next, set the value 0071 obtained by adding 1 to the line number C1l of the error state holding file 5 as the value of the line number 818 of the record B8, and output the error state C21 of the error state holding file 5 as the source image of the record B8 of the subfile 12. / Copy to error state B28 (step 233).

Next, the process returns to step 231, reads the next record C2 from the error status holding file 5, and learns from the value of line number C12 that the next error has occurred at line number value 0080. Record A8 with line number A18 is copied to record B9 of output subfile 12 (step 232).

Next, set the value 0081 obtained by adding 1 to the line number C12 of the error state holding file 5 as the value of the line number B110 of the record 810, and set the error state C2 of the error state holding file 5 as the value of the line number B110 of the record 810.
2 to the source image/error state B 210 of record 810 of output subfile 12 (step 23
3).

Next, the process returns to step 231 and all records in the error status holding file 5 have been processed, so step 234
Control is transferred to the remaining records A9. of the input subfile 11 that have not yet been copied to the output subfile 12. A
Output 10 Records Bll, B12 of subfile 12
(step 234) and ends the process.

In this way, the output subfile 12 in which the source image and error status of the source program A are arranged in line number order is created on the source program library 1, so the output subfile 12 is referred to by the screen editor, and
This has the advantage that error conditions in the source program can be easily corrected.

[Effects of the Invention] According to the present invention, the source program and error status can be displayed on one screen immediately after compilation is completed, so the source program can be modified without waiting for the compilation list to be output from the printer. This has the effect of increasing program productivity.

Furthermore, the number of output sheets of consoles and file lists can be significantly reduced, resulting in the effect of resource saving.
