First, I think you might have an error in the code you submitted. I assume that
$names{$refnum} = $str;
should be
$names{$ref} = $str;
Second, the reason the code is dying is because on the last line, $names{$number} does not exist.
It might be a good idea to take a look at what $names is actually holding after the loop. A good way to see that is to use Data::Dumper
#!/usr/bin/perl
use Data::Dumper;
%names;
{
open(name, "<data/gly.txt");
while(<name>) {
($ref, $str) = split /\|/;
$names{$ref} = $str;
}
}
print Dumper(%names);
This will help you track down the problem.

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).
