Crystal Reports: How to parse a stringvar array

CR 8.5
i need assistance with parsing a string.

stringvar array array1

example elements in array1:

array[1]=hammer,4
array[2]=nails,3

i need to parse array1[1] so that hammer is stored in one string and 4 is stored in another.
stringvar tempstring1;
stringvar tempstring2;

so tempstring1 will be hammer and tempstring2 will be 4

thanks
