Abnormal termination of a task

If the exit code ends with an ABEND command, or if there is no active exit code, abnormal termination of a task starts after all active program-level abend exits (if any) have executed.

The sequence of actions during abnormal termination of a task depends on the following factors:

Code in the transaction restart program (DFHREST)
Whether the transaction has freed the principal facility
Whether backout was successful
