There's a secret interface called FAMS that can provide the information (and much more for PDSEs), but (as I understand it) you have to convince IBM to let you pay a large amount of money for the documentation.
Ultimately, the directory has to be read to count the blocks, members, etc. There are CBT tools that do this, and FAMS must do it, too. sas On Wed, Mar 6, 2019 at 5:04 PM Kirk Wolf <[email protected]> wrote: > A programming API or macro?
