Program Information Options › Program Comparison

Program Comparison

In most z/OS data centers, many programmers work on the same application systems. This can cause confusion when trying to determine exactly what has changed between different versions of programs. The ability to compare one program to another or one source to another is important because it reinforces the change control procedures at the data center.

Use the Program Comparison option to:

• Compare both source programs and load modules
• Show the differences between old and new source programs and between old and new load modules
• Compare source programs in CA Librarian, Endevor Change Manager or CA Panvalet libraries.

When comparing source programs, CA Auditor determines which source lines were actually deleted, inserted, or changed. This means that, if one line is deleted from a source program, CA Auditor can show just that line number. Similarly, if one line is inserted, CA Auditor indicates the inserted line only. This prevents an entire program from being marked as changed even though only one line is different.

To compare programs

1. From the Primary menu select option 5.

   The Program Information menu is displayed.

2. Select option 3.

   The Program Comparison screen is displayed.

3. Enter the names of two program libraries and two programs to compare. You can also specify whether CA Auditor should ignore or consider sequence numbers when it compares the programs.

   The Load Module Comparison screen displays the results of the comparison of the old and new load modules.

You cannot use the Load Module Comparison function to perform compares of load modules which are already loaded into your TSO address space. Examples of such programs include CA Auditor itself, TSO modules, and ISPF/PDF modules.
