z/OS UNIX overriding file disposition specification - Key = '801A'
DUNOVPDS specifies the file disposition of the z/OS® UNIX file being deallocated. It overrides the disposition assigned to a file when it was allocated.
When you code DUNOVPDS, # must be 1 and LEN must be 1; PARM must
contain one of the following values:
- X'04' - the file is to be deleted
- X'08' - the file is to be kept
Example: To specify that the z/OS UNIX file
being deallocated is deleted, code:
KEY # LEN PARM
801A 0001 0001 04
