All the positive perfect squares 1, 4, 9, 16, 25.... are written in strictly ascending order of magnitude and without the commas and spaces, resulting in the following infinite string:

149162536496481100121144......

Reading left to right, what is the 2010^th digit in the above pattern?

No, wait a minute.  On looking more closely at your QuickBasic code, the problem lies not in the variable initialization, but in the STR$() function like you said.  Maybe it does that to facilitate output formatting?
