Re: Warning messages

>> Use of uninitialized value in numeric gt (>)

For example:
<code&gt;
my $oper1; # not initialized
my $oper2 = 10;
print "blahn" if $oper1 > $oper2; # using $oper1 without a value
&lt;code>

>&gt; Use of uninitialized value in concatenation (.) or string
For example:
<code&gt;
my $str1; # not initialized
my $str2 = "Perl";
print $str1 . $str2; # using $str1 without a value
&lt;code>

HTH.
