The Idiot's Guide to Solving Perl CGI Problems has your answer.

Don't let the name put you off. I had to refer to it for my first Perl CGI scripts, too.

Yikes! You really got that script to work on your computer ? My perl complains loudly when it reaches the <br><br> part.

Now, if you either removed that line or put it in within a print statement, it would at least compile :-)

If you want your program to "work" as a cgi-script you need at least a content-type header

#!/usr/bin/perl -w

use strict;

print "Content-Type: text/plain\n\n";
my $add = '152';
print $add / 321 + 4 * $add, "\n";

And it will not work without 'use strict' or '-w' of course *grin*. And then there are all the other possible errors you might make of course...

Autark.

A good answer, but please note that the two newlines at the end are part of the header and not a replacement for the two break tags you had listed. To "web enable" your code you should use the code Autark posted but add the your tags in a print statement, like this:

#!/usr/bin/perl -w

use strict;

print "Content-Type: text/plain\n\n";
print "<br><br>\n";
my $add = '152';
print $add / 321 + 4 * $add, "\n";

But I think it was just part of his formatting inside the code tags...
