Need Help??

might be a little more informative if you do something such as:

foreach( keys %ENV ) {
   print "$_ = $ENV{$_} \n";
}

Since what varables are available may vary from system to system. Of course just wanting to know "system variables" is sort of a vague question...

Or perhaps more economically, `while(my ($key, $val) = each %ENV) { print "$key = $val\n"; }` [download] since you're not sorting the keys anyway. Makeshifts last the longest.	[reply] [d/l]
