Modifying fields in the command-level parameter structure by exits XNQEREQ and XNQEREQC

The fields that are passed to the enqueue domain are used as input to the request. The correct method of modifying an input field is to create a new copy of it, and to change the address in the command-level parameter list to point to your new data.

Important:
  1. Do not modify an input field by altering the data that is pointed to by the command-level parameter list. To do so would corrupt storage belonging to the application program and would cause a failure when the program attempted to reuse the field.
  2. There are no output fields on EXEC CICS ENQ and DEQ requests.
