This is a weird idea that is floating around in my head. I am wondering if
there is any software which can create a "picture", "diagram", or "flowchart"
of JCL? I'm not too sure if this is even a useful thought. It's just a
scratch that I must itch (or something like that). What this may eventually
morph into is a scheduling diagram showing our production job flow.
A while back, there was a tool that did something similar for CMS pipelines
applications and could step through the operation of the pipeline app and
visualize it. I'm drawing a blank on the name, but I think it was called
PIPETEST or something similar, written by someone at SAS Institute. (There
was a YouTube video of it on developerworks, but it seems to be Yet Another
Missing Document 404 on an IBM website and the developerworks web site is
completely offline at the moment (midday on a business day -- seriously,
IBM?)). I wonder if that could be a good starting point. You'd have to
generate a formal grammar for JCL and then write the interpreter for it, but
the grammar might exist somewhere; on Linux, you could use yacc and lex to
eat a job stream and parse out the various bits you're interested in. It'd be
a lot of footwork, but certainly not impossible.
You might have a look at EHIJCL, my REXX exec to convert JCL into ISPF-like HTML
(in case you need to do a presentation, and don't have access to a live z/OS
system) @ https://prino.neocities.org/zOS/zOS%20Tools.html
It wouldn't be too hard to add exits to the various keyword processing routines.
