I was wondering why, since I do it myself, we don't start
the simple my defs with an initialization by expected type:
my $drvname ='';
my @columns = ();
my %someHash = ();
and then check before 'fixing' the print statement with
something on the order of:
my $msg = "$trd Driver ID:</td><td>";
if (defined($columns[19])) { # with explanation why 19...
$msg .= "$columns[19] -- $drvname</td></tr>";
} else {
$msg .= " -- $drvname</td></tr>";
}
print $msg;
