PURPOSE:To enable visualizing the modification status of a program by writing necessary display items such as program name and revision for distinguishing between programs before and after modification in a revision area and by displaying said items during program execution. CONSTITUTION:When a program is modified, a source program is opened in step 1, program contents are modified, added, deleted, etc., in step 2, and a revision is upped in step 3 at the point of time of completion of rewriting. Next, the new revision, upped revision, is written in the revision-receiving area of the program in step 4, and an assemble is conducted in step 5 to convert said program into an object program 6. Then, the revision written in the step 4 is received by ROM 7. Thus, even if a program is modified, the present program can be displayed accurately. |
