Hi Mike
"I like your enthusiasm, never loose that!"
I won't ! , I promise.
I love Tcl. Basically my favourites are Cobol, Tcl and Ada.
Have you looked at jim tcl ?
It's really small.
This is probably just some more "crack smokin" but I have been day
dreaming about rewriting jim in pure COBOL. Tcl in native cobol
would be neat.
I have printed all of the source of jim in color and I am also
studying tcl parsers written in tcl to lower the bar to entry.
Thanks

Patrick,
Although I agree with Vince, I like your enthusiasm, never loose

As of lately (the last 5 years), I've been doing migration work,
migrating HP3000 applications to Windows, Linux and HPUX (Unix).
Like IBM, HP, specifically the HP3000 has it's own version of
JCL.
Many of the programmers I work with jump right into converting
the JCL to some local scripting language. On windows it would be
BAT files or Power-hell, on Linux its bash scripts, on HPUX its
ksh scripts, and so on......
Much of the JCL originated from batch the processing days, then
the OLTP machines made it more interactive, and on HP MPE/iX
platforms it grew into a very advanced scripting language. So,
for me (to emulate the JCL environment) the replacement for
Batch/JCL is Tcl. For a minute I thought about using NodeJS
instead of Tcl. In the end I choose Tcl, mostly because I can
call "TclEval" directly from Cobol, or C.
Converting all JCL to Tcl makes more sense, because the exact
same Tcl syntax can be used on any of the most popular
platforms, including Windows, Mac, and all flavours of Unix.
Now with GNU being my platform of choice, and becoming more
aligned with the Richard Stallman philosophy, I ponder, should I
trade Tcl, for Guile?

JCL is exactly that a Job control system
for executing/starting jobs on a m/f (mainframe) it links
any resources needed by a specific program or group of
programs, e.g., files and their access type, printers etc.
Yes, some of the commands in it are
inconsistent but that is more the fact that various
programmers have coded the new stuff without sticking to
some standards in format etc.
Under Linux such a process is NOT
required as it is all dealt with inside the existing tools
of Linux.
There is no need for it and more
importantly the old saying
"If it is not broken don't fix it"
comes seriously to mind.
It is a wasted exercise.
