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
