The SQL examples will be great and highly useful to those of us planning on holding onto DDS until IBM pries it from our cold dead fingers. Examples are good. Lots of simple, complete, working examples *isolating* and *illustrating* one or two principles or techniques are extremely valuable learning tools. Not everybody wants to use every technique; I personally feel two simple examples are better than one complex example, and a series of related examples (showing linkages, etc.) is the best of all. The forward: iFrank or eLou? Neither. There are a couple of industrial-strength posters on these lists; you could easily get 10,000 pages of opening comments from any one of them. You could also run a contest and select one or more mini-forwards; of course you wouldn't reveal whose forward(s) you selected; all the submitters would have to wait until publication, when you'd sell at least one copy per submitter! Small comfort, I know, but I wanted to cheer you up. -----Original Message----- From: web400-admin@midrange.com [mailto:web400-admin@midrange.com]On Behalf Of Brad Stone Sent: Tuesday, January 08, 2002 9:33 PM To: web400@midrange.com Subject: Re: [WEB400] First Internet application > Misunderstandings: you provided excellent explanations in > "eRPG".

The first book was just a starter, to get folks familiar with terms and technologies (like the HTTP protocol, HTTP configuration, HTTP APIs, etc..) Something to get you started. Trust me, I could have put together 10000 pages instead of 380 or so.. but I, from experience, find something that is overwhelming to be less than productive in most cases. :) Which is the case for the 2nd book. It's about 90% new material. A lot more code examples, including a whole chapter devoted to GreenYak!. It goes through all of the pieces, step by step, showing some neat techniques not only in eRPG, but Javascript, frames, HTTP headers, etc. I took the time to ask as many readers of the first book as possible what they wanted in the next book. I even think I posted here months ago on the subject asking that question. There are other examples and updated wrappers for the HTTP APIs, just like in CGIDEV. Even EASIER to use now. For example, instead of having to call the QtmhRdStin API and pass it the CONTENT_LENGTH environment variable, there is a new option that does this for you. So you have your choice of how you want to do it. And the biggest change is an introduction to embedded dynamic SQL instead of OPNQRYF for record selection. Like I said, I wanted to keep the first book familiar, and at the time OPNQRYF was familiar. SQL is gaining more acceptance now in place of OPNQRYF, and it's a Heckuva lot easier to use to select data for CGI applications. That's the main draw to Net.Data... and this time I show how it's done with eRPG. Again I didn't overload the book with a lot of stuff that isn't used that often. I stuck with what I have used, and others (collegues, friends, and readers of the first book who shared their success stories) use most often. So, you won't see an explanation of how to use the Retrieve HTTP Directive API or how to use Layers with stylesheets and JavaScript. ;) > > Please let us know when your new book is available! I will! You can count on that! The wheels are turning a bit slow right now because of, well, you know... all the stuff that has happened. But it's in the works. I should think that early 2nd quarter it should be ready to go. I wanted it out earlier, but, things happen. :) IBM probably will never "support" eRPG or promote it, but I can tell you that there are a lot more using it than the industry would have you believe. A LOT more! :) It's people like Mel and Giovanni that are also helping to keep this ship moving! They ties to IBM give an illusion that IBM says it's a good technology. And sometimes that's what is needed (unfortunatly). I encourage everyone to support Mel and Giovanni as well. Speaking of which, who do you guys think would make a great person to write the forward for this next book? I don't think Frank Soltis is available for that. ;) Or e-Lou. _______________________________________________ This is the Web Enabling the AS400 / iSeries (WEB400) mailing list To post a message email: WEB400@midrange.com To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/cgi-bin/listinfo/web400 or email: WEB400-request@midrange.com Before posting, please take a moment to review the archives at http://archive.midrange.com/web400.
