I created a script file to quickly load my preferences call "Dimen.lsp".
It is executed by (load"dimen") as long as; files settings in "Options" "Files" "Support" have a known path subdirectory to the folder (so it can find the lisp file).
Best of luck.
[Wow -- 20 years after the initial post!] That list may be good, but doesn't include the brief explanations and options asked for in Message 1. How similar these things are now to what they were then, I couldn't say [certainly many are the same], but today, >this< would answer that request. It has all System Variables starting with D, so more than they were asking for, but at least includes all the DIM* ones together, with not only short descriptions right there, but you can pick on each to get to the options, defaults, etc.
This is not complete but can be useful just for dims, forget where I found it.
