[Tutor] pattern matching problem

[cgw501@york.ac.uk]

One of the worst I think was doing loads of real spazzy stuff trying to 
split whole files in to lists of letters and use string methods to find the 
first uppercase one.

The re tutorial has sorted it out for me. I figured this was the way to go, 
I just couldn't work out how to get the index value back...but now I can. 
Thanks!

Chris
