What does IEC217I Duplicate Directory Entry Message mean in Assembly / HLASM?
Issued during CLOSE processing (accompanying abend B14) when the STOW macro tries to add a new member name to a partitioned dataset's directory but a member with that exact name already exists there.
Issued during CLOSE processing (accompanying abend B14) when the STOW macro tries to add a new member name to a partitioned dataset's directory but a member with that exact name already exists there.
Rename the member being created, or explicitly delete/replace the existing member first if overwriting it was actually the intent, since a plain STOW add will not silently replace an existing directory entry.
