Formatting the Storage Management Subsystem procedure flow trace table

You may specify the STORAGE 'FLO' parameter to format the SMS procedure flow trace table.

The following command would display the output panel shown in Figure 1:

     VERBEXIT SMSDATA 'STORAGE(7FFE3000,FLO)'

Return entries are indented in the formatted SMS procedure flow trace table for readability.

*Trace entries indicate that a trace record was written to the SMS trace table.

The TOD value at the end of the record is the CPU clock value associated with the record, which you can use to identify a specific trace entry.

The ID value identifies the trace point that was invoked. This is useful when a module contains multiple trace points.
