For a lot more detail of what it provides and how to use it from a
programmer's POV, see
https://bitsavers.org/pdf/dec/pdp10/TOPS20/V7/JSYS_REFERENCE.MEM.txt
If nothing else, I think it'll help in organizing your thoughts on
ways to organize the relevant data structures for what you're
proposing. Adapting CCMD (which is pretty similarly structured) might
be a reasonable place to start as well.
Note that the main issue I have, as far as doing a static
description as you're describing, is that it doesn't allow for
dynamically adjusting available options/values/etc at runtime. It can
adapt for different directory contents or whatever easily enough, but
applying logic to determine what options to allow/disallow, or legal
numeric values depending on previous settings, etc, gets very
difficult.
Of course, this can be resolved by simply saying that such flexibility
isn't supported. I'm just used to expecting it because COMND%
provides it. Yes, most of my programming these days is on TOPS-20.
The joys of being retired ;-)
