SELF-referencing with Perl?

[chicken]

Hey Perl geeks, may I request your help?

You know how in PHP you can do, e.g.:

print "<FORM METHOD=\"GET\" ACTION=\"$PHP_SELF\">\n";

Is there a similar thing in Perl? Certainly it won't be called anything obvious like $PERL_SELF, now, will it?

Grrr. Argh.

Thanks in advance for any advice. I am STUPID! *head bashing into desk*

$0 (zero) is the name of the script that is being run without path information. I think $PHP_SELF is /path/to/file.php. I'm not sure how $0 would work in a CGI, but it may be worth a shot. If you're using CGI.pm, you can use self_url() or url(). You also may be able to find something in %ENV that the web server would hand you, but I don't know what the key name would be.

Thank you so much; self_url() sounds really familiar.
