When your program encounters data that indicates errors have occurred, you should terminate processing. Typically, the IDMS-STATUS routine discovers processing errors and abends your program. You should also terminate processing if a situation exists that makes it impossible to ensure valid results (for example, if you are unable to reaccess a previously obtained database record).
To abnormally terminate a task, issue an ABEND statement that specifies a user-defined abend code. Optionally, you can write a formatted dump to the log file and specify whether previously established abend exits should be invoked or ignored.
For more information on abend exits, see Performing Abend Routines.
