Isodraw Macro ignores the leading zeroes

Hi Gang,

I wrote a macro for giving the ICN numbers in the illustrations. It will ask the user some specific inputs. There is a place where it will ask for the starting and ending value numbers. User would give the starting number as 00001 and ending as 0010 (for example). After running the macro when we see the file name and the ICN number in the file, zeroes in front of the value are ignored and it is displayed as 1 and 10. Why Isodraw ignores the zeroes?.
