The parameter scheme used in WWWC is only the suggested scheme. It is possible to modify your main wwMain server prg to use implied programs and routines, or parse the provided querystring anyway you like. After v2.7, WWWC's CGI object also supports the use of named parameters in the URL instead of positioned.

IOW, the parameter scheme provided is just the suggested parameter scheme. You could rework it pretty much any way you like through modification of your wwMain class.
