<> again...	Can't Post

Ive just returned from my travels and began reading up on the site that kevinR gave me. However I still dont understand the diamond operator.
I have a file called text.txt and it contains

Code

This 
Is  
Five 
Seperate 
Lines

And I wrote a program to process that and print it

Code

while(<text.txt>) { 
chomp; 
print "$_"; 
};

Why isnt this working? All help is appreciated. Thankyou.

Thanks KevinR it works now! You dont have to if you dont want to but could you explain some of the code to me. Specifically the first line.

You can look up the open() function in the perl documentation:

http://perldoc.perl.org/functions/open.html

It will explain the open() function in detail. open() is a very basic function, if you do any file I/O you will want to know how to use it properly. There is also sysopen().
