Ddname specification - Key = '0001'

DDCDDNAM specifies the ddname of the concatenated group that is to be deconcatenated. DDCDDNAM is required for dynamic deconcatenation.

When you code DDCDDNAM, # must be one, LEN is the length of the ddname, up to a maximum of 8, and PARM contains the ddname.

Example: To request the deconcatenation of the group of data sets associated with the ddname DD1, code:

KEY    #      LEN    PARM
0001   0001   0003   C4 C4 F1
