You can write an IPCS exit routine for two types of formatting:

• IPCS formatting: This type of formatting is for unformatted dumps and traces processed by IPCS:
  • SVC dumps
  • Stand-alone dumps
  • ABEND dumps written to SYSMDUMP data sets
  • CTRACE trace data
  • GTFTRACE trace data.
• ABEND/SNAP formatting: This type of formatting is used for formatted dumps. These dumps are:
  • ABEND dumps written to SYSABEND data sets
  • ABEND dumps written to SYSUDUMP data sets
  • SNAP dumps.

The following topics describe these items that you should be aware of when writing an exit routine:

• Conditions on entry to an IPCS exit routine
• Services available to an IPCS exit routine
• Restrictions and limitations of an IPCS exit routine
• Discontinuing processing for an interactive user
• Communication between IPCS exit routines
• External routines invoked by IPCS exit routines
• IPCS data areas and mapping macros to be used by IPCS exit routines
• Conventions for return to the caller of an IPCS exit routine
• Making load libraries available to IPCS
• Using IPCS exit routines to format installation-supplied application trace data
