Thank you for the response. I do know about using references, I have used them here and there to pass something to a function that was not in that function's scope. That's not really what I am looking for here. I was not clear enough. I just really wonder whether it is more efficient to set up my array at point A, or point B in the pseudocode below which is trying illustrate my question:
#!/usr/bin/perl -w
use strict;
my @bigarray = ("insert", "a very", "long list here");#point A
my $thing1 = mySub();
my $thing2 = mySub();
#...etc - using mySub repeatedly
sub mySub {
#point B - should I declare my @bigarray here instead, and why?
for (@bigarray){
#do stuff with array
}
}

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).
