Richard is correct. The only type of CP Owned space the cylinder 0 restriction applies to is TDISK, and CPFMTXA / ICKDSF enforces that restriction when allocating TDISK space.
There are suggestions in various places to avoid cylinder 0 in general, b ut the restriction really only applies to TDISK space. There's nothing wron g with using cylinder 0 for spool or page, as long as you're sure you know what you're doing. - Bill Holder z/VM Development, IBM On Fri, 25 Jul 2008 08:46:53 -0700, Schuh, Richard <[EMAIL PROTECTED]> wrot e: >That is not necessary for either page or spool space.
