COBOL Advanced Demo Session › Option 01: Replace a File Control ID › Review What Happened

Review What Happened

In this part of the demo session the following occurred:

• The demo program was stopped at an automatic breakpoint caused by an incorrect file name.
• You dynamically corrected the file name and resumed program execution.

Replacing the incorrect file name in the demo program allowed you to continue testing that program without recompiling it. Of course, if one of your programs or the CICS FCT has an incorrect file name, you would have to correct the source code.

In this case the error was caused by a simple typo. However, the Replacement Options are useful in many situations. For example:

• You can dynamically change a file name to test a program using a different file. This lets you use a test file without altering the name of the production file hard‑coded in the program.
• You can change a program name or transient data queue name to test a program or queue other than the ones that are hard‑coded.

  Note: This concludes Option 01 of the advanced demo session.
