Why use a regexp when you want equality? `if ( grep { $_ eq $system1 } @system_name ) { ...` [download] Going back to the original question: This is a situation where a hash would be more appropriate: `my %system_name = ( box1 => 1, box2 => 1 ); # ... if ( $system_name{$system1} ) { ...` [download] -- edan	[reply] [d/l] [select]

Re^4: array confusion by edan (Curate) on Jul 05, 2004 at 11:11 UTC
That line is creating an associative array (or hash) with 2 keys, 'box1' and 'box2'. You can then access the elements in the hash with the $hash{key} syntax. You might want to read `perldoc perldata` to get an idea of what this all means. -- edan	[reply]
