That would be usable.

The whole purpose of a webapp is to provide a tool for many users. Can 
you say what the upper limit of users running the same webapp?

That is the nature of CGI. But on a sufficiently powerful service the

A very good start. I am currently writing webapps in runbasic. Sorry to 
say, runbasic looks as though it will never be a finished language. I 
hope GamBas provides us with a seriously good tool to write web

I appreciate all your efforts in this regard.
