What does IEC141I OPEN Failure Message mean in Assembly / HLASM?
The standard companion message to abend S013 — issued when an OPEN macro fails for any of a wide range of reasons encoded in the trailing reason code, such as 013-18 where a partitioned dataset was found but the specific member named in the DSN wasn't in its directory. The message identifies the ddname, job, step, and dataset involved.

The message identifies the ddname, job, step, and dataset involved.
Look up the specific reason code that follows '013-' to narrow down the exact OPEN failure, and for a missing-member case in particular, confirm the member was actually created by an earlier step and that no symbolic substitution built the wrong name.
