Hi, please take a look at this little snippet:
use Data::Dumper;
my $dir=$ARGV[0];
print Dumper(\@ARGV);
print $dir;
print shift;
__END__
D:\tmp\Scripts>z1.pl foo
$VAR1 = [];
Use of uninitialized value $dir in print at D:\tmp\Scripte\z1.pl line
+12.
Use of uninitialized value in print at D:\tmp\Scripte\z1.pl line 14.
D:\tmp\Scripts>perl z1.pl foo
$VAR1 = [
'foo'
];
foofoo
D:\tmp\Scripte>
Big surprise!
It works on Linux, Mac and XP.
OS is Windows7 with ActivePerl.
Whats going on here?
Thank you and regards, Karl

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
