UNIT_NAME
The UNIT_NAME keyword specifies the generic or esoteric unit names.
Syntax
UNIT_NAME=(uuuuuuuu|user_var|$NULL, uuuuuuuu|user_var|$NULL,….)
Note: UNIT_NAME is only applicable to non-SMS, non-VSAM
data sets. It does not apply to VSAM DEFINEs or SMS data sets. When
a data set is allocated as DISP=NEW, the unit name that is used for
matching is the one that is identified with the UNIT= JCL keyword
or equivalent dynamic allocation text unit, or the one defaulted to
by the system. For non-DISP=NEW allocations, the unit name is the
generic unit name as identified in the catalog.
Where:
uuuuuuuu is the 1 - 8 character unit name. Wildcard characters are permitted.
Default
None.
Environments
