Ok, I have a (probably little and fairly lame) code challenge! [ed: which
will probably be ignored 'cause its in Parallax mnemonics and its lame]

I needed a 16bit binary to decimal routine but I'm just about out of
registers. So I came up with a routine that pulls off one digit at a time
and gets rid of each digit by calling an io subroutine.

My best (so far) is 76 words and about 100 best to 500 worst case
instructions executed. Compare that to John Paysons marvel at 48
instructions, about 200 executed and 2 input, 5 output/temp registers. Mine
needs its input in 2 registers, returns the output in another and uses only
one temp register during the computation.

Hint: It's ugly. Think successive approximation.

Its posted already at

but gents and ladies will not cheat and look at it until they have beat it
on their own. <GRIN>

Its in Parallax mnemonics, so use

or

to convert to MicroChip mnemonics

At the risk of striking another blow, what challenge was that?
