The fact that a G00V00 DSN has rolled off and been uncatalogued need not mean that the tape has expired. Even specifying delete in the GDG base definition has minimal effect on a tape dataset.
If memory serves, there are multiple CA-1 options and at least one CA-1 utility program that deal with catalog/TMC synchronization. > -----Original Message----- > From: IBM Mainframe Assembler List [mailto:ASSEMBLER- > l...@listserv.uga.edu] On Behalf Of Hardee, Chuck > Sent: Friday, February 12, 2016 3:17 AM > To: ASSEMBLER-LIST@LISTSERV.UGA.EDU > Subject: Reading the CA-1 Tape Catalog > > Hello Everyone, > > I have posted this to the IBM Mainframe and IBM Assembler lists. > > I was wondering if anyone has ever written a program to read the CA-1 Tape Catalog for a > generic name? > In a nutshell, what I am wanting to do is look up in the catalog all entries for a GDG base > name. > > Currently my program issues a call to the IBM Catalog Search Interface (CSI) program, > IGGCSI00, passing the GDG name and I get back all entries that are currently cataloged. > However, if I go to CA-1's TSO Inquiry panel and put in the GDG name modified to have a > low level qualifier of "-" (CA-1's equivalent of "*"), I get back 621 entries.
