I disagree, Ed. Reading a list of destinations from a "parmlib"-type
dataset can be the easiest, and best way, to handle this situation. But
updates to this dataset should be controled and audited, just like a
PROCLIB or any other control-related library. Make provision for
comments in the destination list and it doesn't have to degenerate into
a boar's nest, nor does it need to be so specialized that nobody can
understand it.
IIRC, the DYNAM subroutine from the CBTTAPE site has provisions for the
appropriate SYSOUT dynamic allocation, and FREE=CLOSE can save a DYNAM call.

destination changes you must remember to recompile the
program.
What about writing the COBOL (or any other language)
program so that
destination(s) and other variable changes can be read from
a dataset instead
of hardcoding it or writing such things in JCL?
There is thus only one compile/test action and many changes
in
the 'parameter' dataset on as needed base.
Any better ideas?
I wrote earlier about this issue the semi hidden file. It is not a practical
thing as people leave the company and forget about this hidden file (more like
undocumented). I truly like JCL as JCL is in a proclib where everybody can use
file aid (or whatever) to scan. KISS methodolgy is this case for the it.
