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?

I use Just BASIC (justbasic.com), some freeware I found a while back and got comfortable with.  So I guess QuickBasic initializes a string to a blank character automatically, as opposed to an empty string.
