Hi Ken,
Try the following:
my $q = new CGI;
if (defined $q->param('data')) {
#
# data was a parameter...
#
}
else {
#
# data was not a parameter...
#
}
cheers,
simran.

James,
Do you have to use CGI.pm? Why not use the Apache::Request module?
It's much quicker and powerful, IMO. $apr->path_info() should work
just fine for you, but it's only going to give you the "data" part of
"/script.pl?data."
Also, if you're going to stick to using CGI.pm, why are you saying
"$cgi->param{'foo'}" and not making the method call,
"$cgi->param('foo')"?
