[LA.pm] alternating...

[William Reardon]

Your snippet by itself works, so you must be doing something wrong 
elsewhere in the script.  Are you messing with $line anywhere?  Make 
sure you have warnings on ("use warnings" at the top) and see what 
that says.

Here's an easier way to do the same thing, using the modulo operator:

my @mem = qw|foo bar baz bang bong bing ding dong dang|;

my $n = 0;
foreach my $line (@mem) {
   print '<TR><TD BGCOLOR="',
     $n++ % 2 ? '#93c0c0' : '#cae8ff',
       "<A HREF='$line'>$line</A></TD></TR>\n\n";
}
