Thanks for the link.

In Perl you can replace
#!/usr/bin/perl -w
with
#!/usr/bin/env perl
$^W=1;
or
#!/usr/bin/env perl
use English;
$WARNING=1;
It is described in Larry Wall's book. Maybe many Perl programmers are
not aware of this because it is not always easy to guess a good
keyword to search for in the index. I must admit that I spent some
time to find it out too.
Regards,
Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
