in reply to Pass the value from perl script to html page

It's hard to tell what you intend from your post, however HTML has forms with GET and POST methods. CGI is particularly useful in developing such applications/pages (see also Tutorials). If you're just trying to print to the browser from a cgi:

#!/usr/bin/perl

print <<HEADERS;
Content-Type: text/html
HEADERS

print "\n";

print <<PAGE;
PAGE

To output a variable, merely include it within the heredoc and it will be interpolated.

For an example using CGI, consult the synopsis of the linked pod.

      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>

      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.
