DR>   How do can I read the individual bits that are inside a byte?
Howdy David,
Try the subroutine at the foot.  Don't forget to put DIM Kf%(16) before you
call it.  The remarks are intended for translating the keyboard status byte 
but will work for any integer.
If you only need to check one bit, just use the appropriate line in your 
de.
Something like:
Kf% = 255
CALL GetBinary(Kf%, Kf%())
LOCATE 10, 5: PRINT "Byte contents:  ";
FOR X% = 1 TO 16
    IF Kf%(X%) THEN PRINT "X"; ELSE PRINT "0";
    PRINT "  ";
NEXT X%
Should let you display what's in Kf% as Binary.  To reverse the process:
Kf% = Kf% OR 32  ' Would always set bit 6
   or
Kf% = Kf% AND 32  ' Would zero everything but bit 6.  If it results in
                  ' Kf% = 0 then bit 6 was not originally set.
