8 bit idiot

When you select "A" from the menu, how do you get the computer/DOS to display all the files on the disk on a single page? After 40 years give or take, I've forgotten how and can't find any refrance to it in the DOS manual. Thanks in advance.

Hello all, Newbie here. I remember Electronic Games monthly magazine very well. Great articles and tons of information. Loved it! Got all kinds of ideas from that magazine. Also loved the Computer shopper. Miss them both.
