Re: A83: IS>(


Thanks a lot!  The only problem I see with this is that the 'a' register is
only an 8 bit register thereby leaving me to have only the numbers from
0-255 in my system variables I and N.  For the purposes of my program, I am
going to need to be able to use numbers greater than 10,000.  I appreciate
your response though and for the time being, 0-255 should work fine!

Thanks again!

Jake
