Output

In addition to the output considerations described in Conventions for Return to Caller for an IPCS Exit Routine the following special output considerations apply to verb exit routines.

A verb exit routine can specify an additional return code in the ABDPL parameter list extension. If a parameter on a user control statement contains an error, the parameter list pointer, ADPLOPTR, in the extension should be changed by the exit to a code of 04, 08, or 12. This code causes IPCS to print an error message on the SYSPRINT data set.

The following shows the user control statement error codes and their corresponding messages:

Code: Message
04: Delimiter error in operand field, which contains the parameters
08: Incorrect parameter
12: Syntax error in the parameters
