- That doesn't really answer my question, since (a) not everyone is
- running SMS (we're not) (yet?), and (b) not all volumes wil be SMS,
- and (c) even with SMS, using guaranteed space, wouldn't the UNIT=
- still be required?
-
- Specifically, if ALTRES (for example) is permanently resident, why
- do the following fail without UNIT=nnnn?
-
- //OLD DD DISP=SHR,DSN=SYS1.LINKLIB,VOL=SER=ALTRES
- //NEW DD DISP=(NEW,KEEP),DSN=SYSX.LINKLIB,VOL=SER=ALTRES,
- // SPACE=...,DCB=...
