Unallocation at CLOSE specification - Key = '001C'

DALCLOSE requests unallocation when a DCB is closed rather than at step unallocation. When you code DALCLOSE, # must be zero; LEN and PARM are not specified. See the description of FREE=CLOSE in z/OS MVS JCL Reference for restrictions on the FREE parameter.

Note: The DALCLOSE text unit is ignored for VSAM data sets.

Example:: To specify unallocation at CLOSE, code

KEY   #     LEN  PARM
001C  0000  -    -
