Copy DD specification - Key = '800D'

DALREFD specifies the name of the JCL DD statement from which the attributes are to be copied.

The name can be a ddname, a stepname.ddname, or a stepname.procstepname.ddname where ddname is the label on a JCL DD statement, and stepname and procstepname are labels that appear on JCL EXEC statements. When you code DALREFD, # must be 1, and LEN is the length of the name field, up to a maximum of 44 (X'2C'), and PARM contains the name.

Example: To copy the data set attributes from the“”: JCL DD statement named SAM, code

KEY    #      LEN    PARM
800D   0001   0003   E2 C1 D4
