When you call your second subroutine, it's going to start through the first loop of your for(), do the four reads, then return. It's never going to do the other 3 loops.
If you want to do the loop four times and then return a list of all the results, you can do that. Create an array before your for() loop starts, then replace your return with a push to that array:
push @results, $foo1, $foo2, $foo3, $foo4;
Then after the for() loop is finished, return @results.

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).
