Is "in use" synonymous with "open"? Squirrely either way. How can the user control the "in use" status? Does either TSO ALLOCATE or BPXWDYN provide a keyword?
They are not the same. You can have a dataset closed, allocated to the step and the in use attribute set or not set.
There is a SVC99 verb code (x'05') to remove the in use attribute. Unfortunately it only removes the in use attribute for the DSN and DD. It does not remove the SYSZVOLS enqueue on a tape volume. Another SVC99 brain deadness when trying to reuse a dynamically allocated output dataset for stacking on the same unit in a application program.
I have no idea if there is a secret keyword for it in BPXWDYN. Alan ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
