Or this.... this only works if it's two adjacent bits (or bits with same index)....

[code]
' compare myByte.0 and myByte.1
MOV W, >>myByte ' get bit1 into bit0 in W
XOR W, myByte ' now XOR with orig. bit0 in myByte; if they are different, bit0 = 1
AND W, #%0000_0001 ' but mask off the other irrelevant bits in W
JZ :notdifferent ' if 0, they are same as last time
:different
