How to Convert String to Varialbe

I need to build a large table with variables in it (ie xNum0,xNum1,xNum2, etc.). I would rather use a loop to do this than hand code the variables. Is it possible to convert a string, such as " xNum" + i to a variable?

Your help is much appreciated.

i = 1
this[“xNum” + i] = 5;

trace(xNum1); // traces 5
