How to trace the execution of the EXEC
Another feature of the EXEC Testing Facility is the ability to review the execution history of the tested EXEC.
Sometimes, an EXEC may branch to a particular statement and it is not apparent how it got there. The debugging trace contains, among other things, all recently executed IMFEXEC statements. This history provides a good indication about the logic path the program has taken. The trace information, similar to system traces, is maintained in a wraparound buffer and wraps after collecting 379 lines of data. The most recent information is always available and the trace buffer never runs out of storage.
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
