Return codes
UERCSYS
Take the system action. This is determined by the value of the
LOCALQ attribute in the local TRANSACTION definition for the
remote transaction:
LOCALQ(YES)
The request is queued locally.
LOCALQ(NO)
‘SYSIDERR’ is returned to the application program.
UERCQUE
Queue the request locally (overriding the LOCALQ(NO) attribute, if
specified).
UERCIGN
Override the LOCALQ(YES) attribute, if specified, and return with
‘SYSIDERR’.
UERCPURG
Task purged during XPI call.
XPI calls
All can be used.
Important
There is no ‘UERCNORM’ return code at this exit point, because the exit is
invoked after a failure. The choice is whether to take the system default action
or to handle the error in some other way.
