This also comes back to what I said earlier. It may be worth going to an HLL
demo compiler to do the parsing of the incoming strings, and then using the
arithmetic routines of the HLL. With C18 freely available it may be worth
looking at an 18F chip anyway for the memory size, if Jinx ends up having to
deal with umpteen formatting possibilities.
