Post by thread:[PIC]: hex2dec revisited

I posted this a while ago - with no response. I feel that it's worth looking into, though, especially for Scott.

Yes. and i'm nowhere near skilled enough to fix it, so i used instead: http://204.210.50.240/techref/microchip/math/radix/b2bu-16b5d.htm and had it up and running in minutes. alice -- http://www.piclist.com hint: To leave the PICList EraseMEpiclist-unsubscribe-requestspam_OUTTakeThisOuTmitvma.mit.edu

Andrew, are you sure it doesn't work? Examples? I vaguely remember to assemble and run it without any problems...
