It doesn't, the line starts with a '#' so it is ignored. You have to tell MS-Windows to associate .pl files with perl.exe. Then the OS does what #! was supposed to. But it will always use the same copy of perl.exe, so you don't get the ability to use different releases for different scripts.

I just tested with Strawberry Perl v5.12.1 in Windows XP with the following code: #!/usr/bin/perl -w my @a; my $b = @a[0]; __END__ When run, I get: Scalar value @a[0] better written as $a[0] at test.pl line 4. So yes, it does seem to work, but I think that 'use warnings;' is best practice anyway, as Shawn pointed out. -- Brandon McCaig <http://www.bamccaig.com> <bamcc...@gmail.com> V zrna gur orfg jvgu jung V fnl.
