Re: LZ: Help with a routine



Sure.  BIT is easy.  All it does is compliment the bit you test and 
then puts that in the zero flag.
For example:
    BIT 7,a
tests the MSB of the accumulator.  If the bit is 1, then the zero 
flag is cleared, indicating "not zero".  (Right?)  If the bit is 0, 
then the zero flag is set, indicating "zero".


Got that?  ;)
