REPEAT
by J Gallagher
from Micro Adventurer, January 1984

One of the disadvantages of any sort of input on the ZX81 is the
computer's lack of any auto-repeat facility on its keys. This program
gives you just that. It works by intercepting the display interrupt
(called 50 times a second) using interrupt mode 2. The routine is held
at 7F20 onwards. [Actually 7F01 onwards. JimG]
	If a key is held down for a short while (adjust this by
poking 32566 [7F36] with a value from one to 255) then the routine
continuously sets the debounce system variable to 0, making the
operating system think it has received a new keypress.
	Enter the hex loader followed by the hex code in the dis-
assembled listing. Delete lines 10-90 and then enter the second
program. RUN to save. To call the routine RAND USR 32537.
