PIC Microcontoller Bit Math Method

AND two bits

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
