Please don't misuse the code tags.
Use <p> tags in front of your text paragraphs, and keep the code tags for the real code sections. Thanks.
Your line 123 is reached and executed whether $gSDDdata[$sdd]{source} and/or $gSRSData[$srs]{sect} are defined or not.
Is that really what you want?
Maybe you want to take some action where you print your "m" and "n" (e.g. continue with the next loop)?
update: example added:
#!/usr/bin/perl
use strict;
use warnings;
my @out = ( 1, undef, 3 );
my @in = ( 4, 5, undef );
OUTER:
for my $o ( @out ) {
INNER:
for my $i ( @in ) {
if ( !defined $o ) {
next OUTER;
}
if ( !defined $i ) {
next INNER;
}
printf "\$o(%d) * \$i(%d) = %d\n", $o, $i, $o * $i;
}
}
update2: modified code;

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).

or How to display code and escape characters
are good places to start.
