JFCBDQTY is the contents of the JCL directory space parameter, not that of the PDS to which it refers. All of the JFCB is like that.
You could always open the dataset RECFM=U and read until you got to the end of the directory. I've forgotten at this moment how to tell the end of the directory but I'm sure someone else will chime in (or you could experiment - probably something to do with an entry of all x'FF' or something like that). You would think it would be in the DSCB-1 but I don't see it there. DESERV GET_ALL tells you the number of directory entries.

I thought RDJFCB would work but that does not have the JFCBDQTY field filled in. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
