Obviously setting, or clearing a bit is done with bsf and bcf. Toggleing a bit is done with XOR and a mask. But what if you don't know which bit to set, clear or toggle before the program is compiled?
Using the code below, two bits will be "ANDed" together to find set/reset a third bit.bsf Result ; Assume the result is True btfsc BitA ; If BitA != 1 then result is False btfss BitB ; If BitB == 0 then result is False bcf Result ; Result is False, Reset the Bit
