You could have an ACS code rule that says If PGM=cobol compiler and DD = SYSUT* then dataclas=onevol
Where Onevol is defined in the data class to have a VOLCOUNT of 1 Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Charles Mills > Sent: Wednesday, October 16, 2013 3:32 PM > To: [email protected] > Subject: Unit-count default with UNIT=group-name? > > I'm looking at the Enterprise COBOL V5.1 U/G which says that SYSUT5, 6, 7 and > 15 must all be single-volume allocations. > > If I code SPACE=(CYL,(2,2,0)),UNIT=SYSDA is that implicitly a request for only > one volume, or might z/OS give me one cylinder each on two volumes or a > secondary allocation on a second device (assuming, of course, that SYSDA were > multiple volumes, as it usually would be)?
