Since it looks like he/she is not using strict, that line could make sense if there is a global variable named $filekey that has a value. It is still a bad idea though. #!/usr/bin/perl use warnings; $foo = "Hello"; my $foo = $foo . " World"; print "foo is $foo main::foo is $main::foo\n"; -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
