it shouldn't be a problem (I will test it myself)

my memory needs to be refreshed about CGI: in which case QUERY_STRING is
used? GET or POST or both?

well this is a good solution :-)

what do you mean? ../.. doesn't work?

yes this could be added as an option (to put all the output only into
one file).

so what solution would you propose?

I would like you to send an example html page to use this CGI (or if you
put it already online an URL :-)

thanks a lot :-)

I'm taking a look at it :-)))
