You're using what's called a template. You can do by hand something like this:

here's the html file, let's call it "test.html":

<html>
<body>
%MESSAGE%
</body>
</html>

[download]

here's the perl script

#!/usr/bin/perl -w

use strict;

open HTML, "test.html" or die "can't open html file!\n";

# read the whole file in a variable
my $htmldata=join '', <HTML>;

close HTML;

# prepare the message to display
my $parameter=shift;
my $message;

if ($parameter >0) { $message="Oh no!"}
elsif ($parameter<0) { $message="Really?"}
else {$message="Mwahahahaha!"}

# replace %MESSAGE% by whatever you want
$htmldata =~ s/\%MESSAGE%/$message/;

# display the modified html
print $htmldata

Try running this script with a parameter like 0, 3, -5 and see what's happening.

of course that's really the quick n' dirty way. The Right Way is to use appropriate modules : CGI to manage the input/output from/to the web server, and HTML::Template to manage the HTML templating.
