I *think* (too involved in something else to open the manuals) that SVC 99 information retrieval will give you this information for an open or not open DD name.

I suppose it might. Does the OP also want >to distinguish the cases of: Don’t care about UNIX. Yes, it is in some of my assembler programs. I have a bunch of PDS utility batch programs that have worked fine for PDS. But for PDSe not so much. On a PDS...reading the directory...a use MACRF=R,RECFM=U....works great. On a PDSE...reading the directory....it looks like I need MACRF=R,RECFM=FB. We have both PDS's and PDSe's everywhere. So, I would like to Open the DD, then determine what type of PDS it is, then process file. I may have to close, change DCB field and re-open. Or determine what type of PDS a file is before opening it...if that's possible. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
