*CPSD - Compare Programs

Purpose

This utility compares two programs and produces a listing on the printer of all the changes that would have to be made to make one program identical with the other.

Procedure

To run this utility from Thoroughbred Basic Console Mode, type:

RUN “*CPSD” and press Enter.

To select this utility from the Thoroughbred Basic Utilities Menu, type one of the following:

C and press Enter.

*C and press Enter.

*CPSD and press Enter.

Menu option # and press Enter.

The following message is displayed:

SELECT PRINTER: xx xx: (where xx is a configured printer)

Make your printer selection from the list of available printers displayed in the prompt. Printers displayed in background mode are currently being used by another task and, therefore, are unavailable. If the printer requested cannot be opened, the user is prompted to make another selection. If only one printer is configured that printer is automatically selected.

DISK NAME OR NUMBER:
OLD PROGRAM:

Enter the name of the program to be updated. Program names are any string of 8 characters or less used to name a program and its program file. If the specified program cannot be opened, or if it is not a program, the user is prompted to enter another name. When a valid name is entered, the system prompts:

DISK NAME OR NUMBER
NEW PROGRAM

Enter the name of the program to be used for the comparison. If the program name entered is not valid (i.e., not a program, not on the disk, etc.), the user is prompted to enter another.

Notes

This utility detects three types of changes:

  1. If a statement exists in the old program, but not in the new program, a delete line is printed.
  2. If a statement exists in the new program, but not in the old program, an add line is printed.
  3. If a statement exists in both programs, but its contents have changed, a change message is printed.

If no differences are found, the message PROGRAMS ARE IDENTICAL is displayed.
