I am NOT suggesting this, but I thought I would chime in. You
can modify the stack paramaters directly: use strict;
sub test {
if( $_[0] =~ /regex/ ) {
$_[1] = "match";
}
else {
$_[1] = "no match";
}
}
my $bool;
test( "foo", $bool );
print "foo: $bool\n";
test( "regex", $bool );
print "regex: $bool\n";
That is just silly though. Use the 'vars' method mentioned
above or just have your subs return a value instead of setting
a global variable if that is possible.
You can also encapsulate a my'd variable and make it semi
global via subroutine calls, but this is sort of silly also: use strict;
{
my $foo;
sub setFoo{
$foo = shift;
}
sub getFoo{
return $foo;
}
}

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).
