Hi. Here's an EASY question:
How to check whether the difference is zero?

movlw   .67
subwf   BYTE_TO_CHECK
btfsc   STATUS,Z
<command 1>
<other command>

If BYTE_TO_CHECK is .67, the result of the thrird instruction will be zero
(67-67=0).
My questions:
* If the diff. is 0, will the Z flag of STATUS be set or cleared?
* In the above code: Will <command 1> be executed if BYTE_TO_CHECK is .67?

Thanx for your time.
