That way you can enter as many numeric as possible. (up to 10 if using LONGS)
Thank you Dave for the answer. I thought there cold be a magic way like when converting a variable into ascii using "dec".

I never used long (I don't even know how to commence) can you give me some hint?

I am running short of memory space ( using pic18f2620) could long create memory problem?

Thank you again for your support.
