The most important thing that it does is force you to declare all variables before using them.
This makes writing bug-free code easier because without it you could accidentally use two different spelling of a variable, and perl would use them as two different variables.

You declare variables with the word 'my'. e.g.
   my $First;
   my $Second = "Number two";

Type "perdoc strict" at the unix prompt to find out all the details.

Sorry, "perldoc strict".

On a PC you can read
C:\Apps\Perl\html\lib\strict.html
(adjust the path to match your setup).
