COBOL Advanced Monitoring Features › Backtrace Facility

Backtrace Facility

When your program stops at a breakpoint, you might find it useful to examine the Backtrace Summary and the Source Listing Backtrace. The backtrace facility shows the logic flow of the program and explains how processing reached this point.

The backtrace facility lets you do the following actions:

• View the backtrace summary screen for a (high‑level) summary of the program's execution
• Use special PF keys to step through the program's execution path
• Reposition the source listing to view the program's execution path from a different backtrace position

In addition to the Backtrace PF keys, all other source listing options, such as the Keep window, setting and removing breakpoints, and the ability to scroll backward and forward from the current source listing position are available from the Source Listing Backtrace screen.
