Hello,   I am trying to use a file register as a mask to clear a bit on
PORTB. I do get a warning when I compile:

 Warning[202] E:\PIC\CODE\test.ASM 113 : Argument out of range.  Least
significant bits used.

Here is the code:
Let's say test = 1 for argument's sake (I've tested this and it does)
  movwf   test           ;save request
  movlw   .1             ;need to subtract 1 so range is from 0 to 7
  subwf   test, W        ;w = test - 1
  movwf   test           ;test = test - 1    test = 0
  bcf   PORTB, test      ;clear PORTB.0

It doesn't matter what bit I want to clear, bit five is the only one that
is ever cleared regardless of the value of test. I should point out that
test is in files register 0x015, so it makes sense why bit 5 (the lower
nybble) is the only one cleared, but why is it using it's address and not
it's value?

Thanks, Jay
