Save about 15 seconds when you save or load. Add this code somewhere in your program (here shown at end) to auto-save:
9995 FOR I=1 TO 22
9996 SCROLL
9997 NEXT I
9998 SAVE "NAME"
SAVE with RUN 9995. Each SCROLL execution collapses the bottom line; 22 rounds collapse the whole display except last two edit lines. In SLOW the computer takes a while to unscroll to full screen.
