Single-Stepping

Press PF9 or PF10 to execute a single machine instruction, COBOL verb, or PL/I statement, as indicated in the PF key definition on the bottom of the screen. Use this method to see what data values are being moved into main storage.

Notes:

• The step amount for PF9 and PF10 cannot be changed. However, select alternative step amounts by entering CNTL commands or by using the Resume Menu options. Access the Resume menu using PF6, and select Option 4 Resume (the fast-path command is =4).
• When you use PF10 to single‑step through nested COBOL IF statements, it might appear that CA InterTest for CICS is not executing one verb at a time. This is a function of how the compiler generates the object code. To follow closely the execution of nested IFs, use PF9 (execute 1 instruction) instead.
