DCB reference to a ddname specification - Key = '002D'

DALDCBDD specifies that DCB information is to be retrieved from the currently allocated data set associated with the specified ddname. For time-sharing users, the expiration date and INPUT/OUTPUT ONLY specifications are also retrieved. This key is mutually exclusive with DCB reference to a dsname (the DALDCBDS key). Any DCB attributes, expiration date (DALEXPD), and INPUT/OUTPUT ONLY (DALINOUT) keys specified in addition to this key override the corresponding DCB parameters associated with the ddname.

When you code DALDCBDD, # must be one, LEN is the length of the ddname, and PARM contains the ddname.

Example: To specify DCB reference to the ddname DD1,: code

KEY    #      LEN    PARM
002D   0001   0003   C4 C4 F1
