ABEND codes

ABEND Code U-0013 or U0013 (X'000D') is issued when a failure or error condition occurs for which normal program execution cannot continue. An associated Reason Code (usually contained in general register 15 at the time of the ABEND) further describes the condition.

The Reason Code is an 8-digit hexadecimal value of the form mmmmrrrr where:
  • mmmm (the high order 4 digits) is the Binary Coded Decimal representation of an associated message number. If these digits are 0000 no message has been issued.
  • rrrr (the low order 4 digits) is a Reason Code that identifies the failure or error condition.
Unless otherwise indicated, the following items apply to all Reason Codes:
System Action
The system may create LOGREC records and may also create an SVC dump.
System Programmer Response
Search problem reporting databases for a solution to the problem. If no solution exists, gather the following diagnostic and problem determination materials and contact the IBM Support Center:
  • Binary machine-readable dump data sets (e.g., SVC dumb or SYSMDUMP data sets). (Print image formatted dumps written to data sets referenced by the SYSUDUMP and SYSABEND DD statements are, in general, inadequate for determining the source of the problem.)
  • Formatted LOGREC records related to the failure. Refer to the Environmental Record Editing and Printing Program (EREP) User's Guide GC35-0151, and the Environmental Record Editing and Printing Program (EREP) Reference GC35-0152 for information on the selection and formatting of LOGREC records.
  • Relevant sections of the MVS System Log.
