Generally Keyword parameters having their value as '*' will
be referred as Backward reference, which means the value of
the Paramater depends on the previous lines of the JCL.
EX:
Sysout=* will refer the Msgclass value in the job card.
DSN=*.step1.DD1 Will copy the DSN value of step(step1)of DD
stmt DD1.
Similarly, we can refer back the following parameters.
1) Vol=ser
2) DCB
3) Disp
I hope this answered your question.
