This would help if you don't want to modify your code much

#!/usr/bin/perl
use warnings;
use strict;

my $List = "/bin/ls";
my $tmp = "/tmp";
my $var = "/var";
my ($Results1, $Results2);
&DoList();

print "Tmp is\n$Results1\n";

print "Var is\n$Results2\n";

sub DoList {
    $Results1 = `$List $tmp`;
    $Results2 = `$List $var`;
}

But mind this..global variables are discouraged in larger scripts.The safe thing is to assign the return value(s) as suggested by moritz.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
