Putting it differently, there is no distinction between "member data space" and "directory entry space." Being out of one is being out of both. A PDSE of 10 tracks could equally well hold one member of ~500K or lots and lots of tiny or "null" members. A mischievous programmer adding an unbounded number of empty members would be no different in effect from a mischievous programmer adding one member of unbounded size.

This is NOT directory full, it is lack of space. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
