Fill-Out Form through WWW Common Gateway Interface

FILL-OUT FORMS THROUGH WWW COMMON GATEWAY INTERFACE

The following examples demonstrate Common Gateway Interface. The source code for decoding these examples is a simple Ch CGI program called form.ch. If Ch CGI has been setup properly in your Web server, this program is located in your_web_server_cgi-bin/chcgi/form.ch. This Ch program can handle both METHOD=POST and METHOD=GET.

Example 1 -- a ludicrously simple fill-out form.
