71B: DISP, KEY$, and keyboard buffer

[Dave Britten]

Nah, just so I can stop the output and read it leisurely, then continue the program when I'm done reading. No different from putting an R/S in the middle of an RPN program, really. Sometimes you want an R/S (DELAY 8,8), sometimes you want a PSE (DELAY .85,.125 or whatever your preference). Makes it easier to read multiple outputs without the computer getting ahead of you.
