The best I can do is point you here: http://cgidev2.easy400.net/
Personally I wouldn't invest too much in CGIDEV2 at this point. It offers a low entry point, but if you're like me you'll quickly outgrow it. I have CGIDEV2 legacy that I haven't escaped from yet, but I avoid it new work. I use native CGI with RPG, but things like PHP, Python or Node are good choices.

Subject: CGIDEV2 HTML directives
Hi All, I am doing a lot of reading while dipping my toes into the CGIDEV2 ocean. One of the things I found to read was an article in System iNews from April 2008. (yes i still have those magazines laying around.) In the article RPG to the WEB: the CGIDEV2 way by one of our favorite people, Paul Tuohy he says. " ...with the addition of CGIDEV2 directives to identify sections (delimited by <!-- $ and $ -->) and variable names (delimited by <!-- % and % -->)
I have been trying to find a list of all CGIDEV2 directives. If there are more, can someone please point me at them?
