Hello monks, I want to find out if a key in a hash is defined. when I try the following code from http://perldoc.perl.org/functions/exists.html 
print "Exists\n" if exists $hash{$key};

[download]
when i have; 
use strict; use warnings; use diagnostics;

[download]
I get a "use of uninitialized value warning" I know some values are uninitialised, and wanted to use the above function to seperate them out. Is there a way to do this without being warned!? Many thanks for your thoughts.
