It looks like `$temp[1]` has a chr 13 at the end of it. Which OS are you on?	[reply] [d/l]

Did the data in the array originate on Windows, and you chomped it? That would leave a chr 13 at the end of the string. Add `$Data::Dumper::Useqq = 1;` [download] Just before the `print Dumper...`. If, as I suspect, it shows that `$temp[1]` really contains "Test MMA\r", you can use `$temp[1] =~ s/\r//;` [download] to cleanse it. Unless I state otherwise, all my code runs with strict and warnings	[reply] [d/l] [select]

You should try creating another array with just 'Test MMA' in it and give it a try. Or perhaps, you could just try copying the following into a new file and test to see if it works. If it does than you know something is wrong with your array definition. `my $array = ['','Test MMA','Generic key']; my %hash = ( "Common SW Component" => "4885", "Test MMA" => "5130", "Generic key" => "5033", "Another generic key" => "4575", ); my $variable = "@$array[1]"; print "$hash{$variable}\n";` [download]	[reply] [d/l]

Looks like you pasted/edited something funny or there were control characters messing with your cut/paste. This snippet is not legal Perl so it's not what's really there. Make sure to have `use strict` and `use warnings` on. `$VAR1 = [ '', ', 'Test MMA '/dir/k_apps/` [download]	[reply] [d/l] [select]

~~The error is generated because of using a carriage return in a string used as a hash key~~ as shown by the following code: `#!/usr/bin/perl use strict; use warnings; my %hash = ("Common SW Component" => "4885"); my $variable = "foo\r"; print "variable ending with carrige return is =$variable=\n"; print "$hash{$variable}\n";` [download] Output is: `=ariable ending with carrige return is =foo Use of uninitialized value in concatenation (.) or string at try1.pl l +ine 8.` [download] Update:Even without the \r it would fail, simply because the hash value is undef and an attempt is made to print an undefined value.
