STOP IMMEDIATE

The character string STOP IMMEDIATE tells ZDT/Db2 to stop the current ZDT/Db2 function without writing the current record to the primary output data set. Specifying STOP IMMEDIATE on the RETURN instruction results in the current record not being imported to the target table and the Import utility being stopped.

Here are some examples:

RETURN 'STOP IMMEDIATE'
Return 'Stop Immediate'
Return stop immediate  /* assumes variables 'stop' and 'immediate' not assigned */
