Using LU 6.2 User Edit exit routine (optional)

This exit routine edits input and output messages from LU 6.2 devices when the implicit application program interface support is used.

If it is not provided, then messages are presented without modification. IMS does not invoke the exit for CPI-C driven transactions because IMS does not participate in the data flows when the application program uses the CPI directly.

The LU 6.2 User Edit exit routine is called once for each message segment or inbound control flow. You can call the exit routine for data messages and use it to:

  • Examine the contents of a message segment.
  • Change the contents of a message segment.
  • Expand or compact the contents of a message segment.
  • Discard a message segment and process subsequent segments, if any.
  • Use the Deallocate_Abend command to end the conversation.
