I'm not sure if this will help you, Eric, but I created a function called GET_BIT for my March N&V column that lets me extract a bit from any byte -- you could certainly pass the port (RB or RC) and bit position to this function and get a 1 or 0 back.

[code]
' Use: result = GET_BIT value, position
' -- returns 1 or 0 

GET_BIT:
  tmpB1 = __PARAM1				' save value
  tmpB2 = __PARAM2				' save position

  tmpB2 = 1 << tmpB2				' create mask
  tmpB1 = tmpB1 & tmpB2				' isolate bit
  IF tmpB1 > 0 THEN
    tmpB1 = 1
  ENDIF
  RETURN tmpB1
[/code]
