Hey guys,

Thanks for the replies, I was able to get it work with that, I appreciate it. It's not a homework assignment for me. I think it may have been for a friend of mine, it's from a book called "A Little Book on Perl".

My friend took a UNIX class and he got that book with it. I got the book from him, and I'm going through the excercises right now just for fun. I don't have any of the O'Reilly books on Perl, but perhaps I should pick one of those up since they seem to be recommended quite a bit.

I have another quick question here... Another pretty stupid one that seems like it should be pretty obvious, but for some reason when I try it, it doesn't work.

Let's say I have the user enter a four-digit number on the keyboard. Then I want to output the two middle numbers. How would I do something simple like this? If someone could give me a few ideas, that'd be sweet... Thanks Smilie

-Jason
