Well there is a very easy way ( albeit fairly slow :) ) ( I'm using

it as I get digit by digit entered on keyboard ( and user input

tend to be slow if compared to pic-speed :) ) Anyway here goes:

In the case of a 24 bit variable 'allocate' 3 bytes of data

clear them. Add the left mostdigit, multiply by 10 add the next

digit etc. etc. *very* easy albeit slow as said.

24bit*10 can be generated by the code generator.

There are faster way to do this but sofar I haven't had the need for

such an routine.
