That is more or less the solution we are using now: to circumvent the
limitations of PARM= we pipe the template through several steps of the
utility. Every step replaces as much of the variables in the template as
the PARM will allow. I consider this rather clumsy and was looking for a
more elegant solution that could be implemented in a single step.
What we really need of course is variabel substitution in inline data by
the system:
// EXEC PGM=XXX
//SYSIN DD *
PRINT &DATASET(&MEMBER)
/*
//
where JES2, JES3, MVS or whatever treats those &VARs just like JCL
parameters and substitutes the current values. Then I wouldn't have to
figure out how I can retrieve JCL procedure paramater values. I'm sure
every shop would highly appreciate such a feature. This is probably not
the right place to lobby for this feature....

One possible solution is to have a simple program that writes
it's PARM value to a sequential file.
Put several steps of these at the start of your stream, and let
each write DISP=MOD to a parm file (except the first one, which should
create the file or write DISP=NEW). Each step of course has a different
JCL variable as it's PARM.
Then your utility can read the file containing the parameters
rather than using PARM.
You could even have an option - PARM=SYSIN gets from file, else
from PARM.
