Breakpoint Activities › The Backtrace Facility › Navigate Through Program Execution

Navigate Through Program Execution

Trace your program's execution path by performing the following actions:

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

When you first access the Source Listing Backtrace by pressing PF2 on the Backtrace Summary screen, the following screen appears. Access this screen also from any other section of backtrace by pressing PF6, which positions the backtrace at the last statement executed (the current breakpoint).
