I now have the script below. I was slightly surprised it didn't get an error
as I had it load /usr/lib/ocaml/3.08.3/cgi/netcgi.cma, and the directory
contains:

cgi.a       netcgi_env.cmi      netcgi_fcgi.mli         netcgi_jserv.cmi
cgi.cma     netcgi_env.mli      netcgi_jserv_ajp12.cmi  netcgi_jserv.mli
cgi.cmxa    netcgi_fcgi_10.cmi  netcgi_jserv_ajp12.mli  netcgi.mli
META        netcgi_fcgi_10.mli  netcgi_jserv_app.cmi    netcgi_types.cmi
netcgi.cmi  netcgi_fcgi.cmi     netcgi_jserv_app.mli    netcgi_types.mli



When I run it, I get a different and shorter error message:

File "./demo.ml", line 35, characters 2-5:
Syntax error

The line in question is:

    | "1" -> "Yes"

Is there some irritating little syntax error around line 35?
