Code DDNRTDUM to request the return of an indication if the ddname
specified in DDNDDNAM is associated with a dummy data set. When you
code DDNRTDUM, # and LEN must be one, and PARM is a one-byte field.
DYNALLOC sets PARM as follows:
- X'80'
- The ddname is associated with a dummy data set
- X'00'
- Otherwise
Example: To specify that the DUMMY indication
be returned, code:
KEY # LEN PARM
0002 0001 0001 -
