Re: Comparing two strings

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

To give you more insight into what I'm trying to accomplish: If you are
familiar with the word game "Jumble" that can be found in most newspapers, I
am trying to build a program that matches the scrambled letters against a
list of words and finds a match.
