Step Amount

The step amount determines how many COBOL verbs, Assembler instructions, or PL/I statements will be executed at a time when you use PF10 to single‑step through your program.

Stepping Amount=

To set the step amount for PF10, perform the following steps:

1. Type profile on the command line and press Enter, or press PF4 to access the Profile screen from any Source Listing screen.
2. Enter the desired number of COBOL verbs, Assembler instructions, or PL/I statements from 1 to 999 in the Stepping amount= field.
3. Press Enter. When the Source Listing Breakpoint screen is redisplayed, the new step amount is reflected in the PF10 (Single‑step) definition, as shown in the following example.

Example

The Source Listing Breakpoint display in the following figure shows a PF10 step amount set to 004 Verbs.

Note: The step value of PF10 on the Source Listing Breakpoint screen does not apply to the PF10 definition on the Detailed Breakpoint screen.

Use the Stepping Amount parameter to enable the automatic tracing feature of the Source Listing Backtrace. When the Stepping Amount is set to any number greater than one, the new value becomes the number of statements CA InterTest for CICS traces on the Source Listing Backtrace. (PF9 traces backward; PF10 traces forward).
