Depends a bit on what "public" means.

A very common meaning is "visible to public internet".

And there are lots of web servers not available on the internet.

And I would expect the vast majority of VMS web servers to not be
available on the internet.

If you just mean visible outside the data center / server room,
then it is probably most web servers.

That wa smy concern as well.

But it turned out that CGI_SYMBOLS indeed has a capability to write
body to file.
