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?

From: http://www.myke.com/basic.htm

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
