Return ddname extended specification - Key = '0011'

Code DINRTDDX to request the return of the ddname associated with the specified allocation. If the data set you specify is a member of a concatenated group, this key returns the ddname associated with the first data set in the concatenation. Otherwise, this key returns the same information as the DINRTDDN text unit.

When you code this key, # must be one, LEN must be at least the length of the ddname, and can be longer, up to a maximum of 8. The PARM field must be the length specified by the value in LEN. Upon return to your program, PARM will contain the requested ddname, and LEN will be set to its length.

Example: To request the return of the ddname, code:

KEY    #      LEN    PARM
0011   0001   0008   --------
