addition of two numbers which are of character type.

Hi All,

I want to add two numbers which are of character type. I tried assigning the numbers to Packed type or Float type variable & then add, but while assigning char type variable to other type it gives error...'Unable to interpret XXXXXXX as no'.

Please guide, how can two char type numbers be added & addition stored in a char type variable only.

Thanks,

Chetan.
