Answer / praveen b
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.

If a field is declared as a comp-3 field and if we want to sort a dataset based on this field, then how will the sort card be??? e.g- if we want to sort by a field which is defined as a PIC X(5) then we will mention - sort fields=(1,5,ch,a). Likewise if a field is defined as PIC S9(10)COMP-3 then in this case how will the sort field be defined (because in this case a sign is also involved)???
