Charles:

Since the code is known to work (I wouldn't have put it on my web
page if it didn't), the problem must be elsewhere.  Let's start with
the easyest possibility first:

    Is your default radix set to decimal (i.e., is there a "LIST R =
    DEC" line in your source code)?

    If not, the "MOVLW 16" at the start of the routine is being
    interpreted as "MOVLW 22".  To fix this, don't add a "LIST R =
    DEC" to your source; you'll probably break something else that
    assumes hex radix.  Instead, just change that line to "MOVLW
    0x10".

If that wasn't the problem, please post some more details... Like
what result you get for a specific set of inputs.
