Okay, I know that this is a really easy one, but it's been bothering me. I've looked at all kinds of docs, but I can't seem to find an answer to this. I'm sure I'm looking right past the answer, and not seeing it.
How do I scope a variable so it can only be seen in the 'main' section? I _thought_ that 'my' was supposed to handle this but I guess not in the way I was thinking.
Exmple code:
#!/usr/bin/perl -w
use strict;
sub foo();
my $bar = "I can see you";
&foo;
sub foo()
{
print "inside foo: $bar\n";
return(0);
}

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).
