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)? The example in the U/G shows only UNIT=SYSDA,SPACE=(CYL,(1,1)). The JCL Reference says that UNIT=device-address is a request for only a single volume but appears to be silent on UNIT=group-name. It's machine-generated JCL so it is not so simple as "why don't you just code a unit count of 1 and quit worrying about it?" A unit count will require a program change.
