Re: Hash key/value

What exactly do you mean by "not recognized"? Seems to work fine:

#!/usr/bin/perl

$something{'that\'s it'} = "foo";
$something{'thats it\!'} = "bar";

use Data::Dumper;
print Dumper \%something;

__END__
$VAR1 = {
          'that\'s it' => 'foo',
          'thats it\\!' => 'bar'
        };

My apologies, was in a rush when I wrote that. I have a file foo.txt that contains a phrase such as "that's it!". I read the contents of the file, and use the filename (foo) as the value in a hash, with the key being the contents: `$key = "that's it!"; #contents from file foo.txt $value = "foo"; #filename $something{$key} = $value; print $something{$key};` [download] When I try to print the above, nothing is there, however when I remove the ' and !, "foo" is printed. I will play with the suggestions in a short while however. Might realize it's just how I'm doing it. Thank you for the quick replies.	[reply] [d/l]

Maybe you should write some code that fails as you describe? Adding strictures (use strict; use warnings;) to your code and running it I get: `use strict; use warnings; my %something; my $key = "that's it!"; #contents from file foo.txt my $value = "foo"; #filename $something{$key} = $value; print $something{$key};` [download] which prints: `foo` [download] just as I would expect. Can you show me equivelent code that fails? True laziness is hard work	[reply] [d/l] [select]

FireBird34: Your subsequent post indicates your problem is resolved, but just for the record: `>perl -wMstrict -le "my $key = \"that's it!\"; my $value = \"foo\"; my %something; $something{$key} = $value; print $something{$key}; use Data::Dumper; print Dumper \%something; " foo $VAR1 = { 'that\'s it!' => 'foo' };` [download]	[reply] [d/l]
