DOS memory lane ... Those few bytes were important in those days. You probably remember the popularity of TSR (Terminate & Stay Resident) utilities. I think Sidekick was a common TSR. Anyway, these programs would load into memory and stay there, watching for the 'magic keystroke' before they would pop-up on your screen and perform some useful task. Because they were instantly available, people found them convenient. Get enough of them on your system and you'd soon run out of memory for the 'main' program you're trying to run; hence, the value of every last byte. Today, we'd accomplish the same thing with a minimized Windows based program: Instantly available, and doesn't interrupt our 'real' work, but with Windows looking after a much larger physical memory, no worries about contention over system resources. Progress! Cheers, PW.
