>>by lookin at the help file, and if it's not there (most times), I just experiment with the command, or with the program
Fair enough, but expense aside, getting info from help is not different than using books. I though you were recommending someone not use any reference and to learn by experimentation only......this is a little optimistic for any subject other than those that are immediately straightforward.
Personally, I prefer books to learn from than trying to read and absorbe info from the screen. If this is expensive then there are always librararies
