Navigate Through Program Execution

You can trace your program's execution path by using the following PF keys:

• Using PF5, PF9, and PF11 to trace execution backward
• Using PF6, PF10, and PF12 to trace execution forward
• Setting the Source Listing Profile Stepping Amount, and then using PF9 and PF10 to automatically trace the execution backward or forward
