The parallel subroutine subroutine-name in MTF subtask subtask-number ended unexpectedly because of the abnormal termination indicated by the user completion code completion-code and reason code reason-code. If the parallel subroutine wrote any output on the message file before terminating, that output is in the message file for the subtask. This message file is the one referenced by the file definition (DD statement or ALLOCATE command) with the ddname FTERRsss, where sss is the three-digit representation of subtask-number.

The abnormal termination was requested by executing an assembler language ABEND macro instruction or by calling one of the CEE3ABD, SYSABN, or SYSABD callable services, among others. The exact meaning of the user completion code completion-code and reason code reason-code depends on the application that requested the abnormal termination. Some form of information about the meaning of these codes should be available to users of that application.
