Subj: DISABLING KEYS

It is possible to disable the PASTE, LABEL, PRINT, and PAUSE keys during
execution of a BASIC program.
 
The Clock-Cursor-Keyboard background task can be modified, or replaced. A
counter at FF8F makes the keyboard be scanned every 3 times this background
process is executed. You can call 7242(hex) to read a key from the keyboard
input buffer, and check for break or pause by calling 7283(hex).  I'll leave a
fuller explanation to the experts.
