Writing a Perl script in CGI to do this is fairly
straightforward. Unfortunately, it's trickier than this. I can't go
into detail at the moment (gotta be somewhere else momentarily) but if
you can't invoke a CGI script from a standalone web browser, you need
to install a web server to take the CGI invocation and run the program
and then take the results and hand it back to the user. I know why
this is so in theory, but I think it was fairly inane of netscape not
to include some capability (maybe a plugin) to handle standalone
browser situations.

Probably your best bet is using Javascript. I hate saying this
because Javascript is *not* my favorite language for myriad reasons.
However, it won't need an external web server to invoke a Perl script.
