Hi, Perl noob here with a distinctly NoobFresh(TM) scented question.... ;-) Comment out "use strict;" in the below and it all works.... uncomment "use strict" and Perl starts giving me abuse about "Global symbol requires explicit package name". Help !

#!/usr/bin/perl
use strict;
%hash = ( ' Key1', ' Value1');
sub doStringTidy {
        my $string=shift;
        $string =lc($string);
                $string=~s/^\s+//;
                $string=~s/\s+$//;
        return $string;
}
sub doHashTidy {
        my $hash=shift;
        foreach my $k (keys %{hash}) {
                $kv=doStringTidy($k);
                $vv=doStringTidy($hash{$k});
                delete $hash->{$k};
                $hash{$kv} = $vv;
}
}
doHashTidy(\%hash);
foreach my $key ( keys %hash )
{
  print "key:$key, value:$hash{$key}\n";
}

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
