Doesn't CLOSE update it from the DCB?
The approaches posted previously all treated the directory as
sequential. AFAIK, the DS1NOBDB field is not altered unless a
STOW is issued. And it would be interesting to determine whether
the common practice of updating a PDS with a primary ENQ of SHR
has led IBM to add format 1 updates to the STOW logic.
