instream sysin to next step:
STEP1 may have other DDs in it which the user is used to overriding
with //STEP1.ddname DD and so that would require a JCL change for
all users of the PROC. Curiously, as I recall, OS/VS1's JES
work-alike allowed the DSN referback to SYSIN and SYSOUT of a
previous step. For SYSIN, it reread the input. For SYSOUT, it did
the equivalent of a DISP=MOD.
Is this for a single program or for a number of different programs?
If it is for a single program than reassemble it to use SYSIN1 in
lieu of SYSIN. Now write a top-hat program that reads from SYSIN (not
caring if it is a DSN= or *) and writes it to a
DSN=&DSN,DISP=(MOD,PASS) dataset. When done, it XTMLs to the real
program (or ATTACHs it). The second step can just
DSN=&DSN,DISP=(OLD,PASS).
