Trace-Point traces

Entering Y for the third option, LOG TRACE-POINT TRACE, gives you additional trace data from pre-established points in ISMF modules or functions. Used with the inter-module trace, this data provides detailed information about the flow of ISMF modules and functions. The log record consists of:
  • The ID of the trace point
  • The contents of register 1 and register 11 when the trace entry was made
  • Any additional trace data that was recorded.
Figure 1 is an example of the ISPF log with ISMF trace-point entries.
