You can also use a here document to replace all those
prints. You just tell it what you want to be printed plus it'll also interpolate variables (e.g. turn $dog_name into "Fido")
As an example, instead of
print " <HR>\n";
print " <TABLE border=0 width=100% bgcolor=\"\#005533\">\n";
print " <TR><TD>\n";
print "$username\n";
you can write
print <<END;
<HR>
<TABLE border=0 width=100% bgcolor="#005533">
<TR><TD>
$username
END
Instead of
END, it can be any word and that word must appear alone to end the here document.
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
