The gotcha is that length is not zero based, but the other positions are. If you got that, you should be able to make it work. Trying to access a value past the end of the string or before it just throws and exception.

I believe that some of them may have been citizens of Spain, and then Mexico, before Texas won its independence. They came from other southern and eastern states. So, hmmm, do I put down that I am Hispanic on those job application forms? :)
