Getting Value

perlvel has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am getting a string value from a function .A variable is exist by that string value. Need to print the value using the second variable! Example: my $log_dir="hello"; my $name=function1(); // $name has value "log_dir" I want the output as "hello" using the "name" variable. Is that possible? TIA,

Why it's stupid to `use a variable as a variable name' `my %dirs = ( log => "hello", ... }; my $dir_type = function1(); die("Unknown dir type $dir_type\n") if !exists($dirs{$dir_type}); my $dir = $dirs{$dir_type};` [download]	[reply] [d/l]
