Protecting CGI script from being downloaded?

Hello;

I am running Apache on Mac OS X (10.4.9). I am a relative UNIX
newcomer, and have a (hopefully) basic question about protecting a CGI
script from being downloaded.

I have a CGI script that is in the CGI-Executables folder (I think
this the Mac OS X equivalent of the cgi-bin folder). It is a compiled
C script.

I want any user to be able to EXECUTE the script through a web
interface.

But, I want to make sure that nobody can DOWNLOAD the script to their
computer (don't want anyone slse be able to use the script on their
own computer).

I have set the file permissions for the script to 111. Will this do
the job??

Is there anything else I need to think about in order to protect the
script?

Thanks in advance.
