The disk drive whirred. The screen wiped itself and displayed a list: mostly Program command files, or data files holding information for the programs, to judge by their suffixes. assist.com change. com COPY.

A ^was a kilobyte, a thousand little pieces or bytes of information; and the disk drive itself was supposed to hold only 800 K. How could the disk possibly have all these files on it, and such big ones? Maybe this is a bad disk, Dairine thought. It happened sometimes, that a disk was damaged on its way from the factory. Or maybe something was wrong with the directory. Well, let's see if something'll run. Beside the A> prompt she typed "copy" and hit the carriage return. The disk drive whirred. The screen wiped itself again, then said: IIIC COPY UTILITY 5430K FREE RADIUS? Dairine stared again. Radius meant nothing to her. She hit the carriage return, hoping the computer would (as some programs did) supply its own data as a result.
