Referral Type Data

Referral type data is represented in the key entry format as subparameter fields. The pieces of the parameter are defined as delimited by periods. Each piece of the referred-to data is identified by its length and name in the order in which it appears in the statement. The asterisk is the first subparameter defined.

//DD1     DD  DCB=*.STEP1.DD1

Key	Number Parameters	Number Subparms	Length	*	Length Piece 1	Piece 1	Length Piece 2	Piece 2
40	01	83	01	*	05	STEP1	03	DD1

The asterisk is the first subparameter.
The remaining subparameters are the pieces of the referred-to data delimited by periods.

Note: In the “number of subparameters” field, the high-order bit is always set on.
