John,
Interesting idea and it might work if all DD statements were in one
program.
(Not called subprograms etc).

We had a discussion on changes we would like to see in JCL. Well, I am
wondering if perhaps what should be embraced in a variation of Knuth's
"Literate Programming" in which the program source is actually
embedded in
the documentation. I am wondering if some JCL documentation company
might
consider this to be something as a possibility for a product. This
would
combine and centralize the maintenance of the JCL with the
documentation
for the job.
Combining this with the DCF thread, how about something like DCF's GML
which could be run through some program. One DD would output the
JCL, such
as could be sent to the internal reader. Another DD would contain
formatted
text, such as AFP or PDF output. Might even be nice if this vendor
program
could be written so that a scheduler program, such as CA-7, could
use it as
a "preprocessor" for jobs that it submits. This would be so that
the CA-7
JCL library would contain the "Literate JCL" and be able to "directly"
submit it. Of course, said vendor product should also be able to do
a JCL
syntax scan to detect syntactic JCL errors.
Just a wacked out thought for the new year.

This is clearly another case of too many mad scientists, and not
enough
hunchbacks.
