i am one of those people who never quite learned DOS--my first computer-- a TI99/4A didn't use it, and i kept that from 1981 till 1993- and then got a computer with windows 3.1 i need to learn a little DOS, but never got good at it.

in 1996 or 97, the CEO of a company i worked at was still using a DOS based application.. and he expected me to do a project using the old software..

things were fine, except if i needed to edit a file (it was a DB application) --at one point, frustrated by the app, i told him, I could accomplish more if i could RTFM-- and he asked "what?-- i replied "if i could Read The Manual.." he started to ask-- "RTFM--what does the F stand..??" blushed, and said "never mind!"
