I have been involved with IBM's midrange computer lines since 1975. In my opinion, the AS/400 is the finest combination of hardware and operating system that has ever come to the business market. It is truly a "programmers' machine" and its reliability is legendary.

I am a contract programmer and work exclusively in the Austin, Texas area. I prefer long term assignments and would be happy to discuss your requirements. If I can answer any questions you may have or suggestions for this web page, please feel free to call or Email me.

His commentary is well worth the read for any fans of News/400 that have felt jilted by the move to a membership system. With his permission, I am posting his response here

Shields Up This site is a "Must See". It greets you with your name. Kind of scary, isn't it? If you're using cable modem, DSL or ISDN, you need to spend some time at this site. It includes two benign probes that test your firewall. This is one of the best I've found concerning security.

Favorite Tips and Techniques

I recently worked on a CISC to RISC conversion. The most interesting problem we encountered was move some 6,000 spool files form the old to the new AS/400. We evaluated several commercial options and chose to do it on our own. If you're interested in how we did it, let me know.

This tip also courtesy of NEWSWire/400:
NEW AS/400-SPECIFIC ENCYCLOPEDIA AVAILABLE ONLINE Whether you have a nagging question about the AS/400 or need a handy training reference for new employees, you might want to check out IBM's searchable online guide to AS/400 computing, AS/400 Encyclopedia. The guide has more than 250 entries on short topics, and its four "volumes" cover AS/400 systems and technology, options and peripherals, software, and communications. To check out the Encyclopedia, go to http://www.as400.ibm.com -- it has a link from the home page at the moment (you can also find it under "Reference Library" in the left navigation frame).

I've found that the first time you tackle a new feature on the AS/400 (or any other machine for that matter) it takes a while to get over the learning curve. IBM has published documents called "Redbooks" for years . These handy books will usually give practical, step by step instructions on how to use features, hardware and programming techniques.

Redbooks, named for their red covers, are "how to" books, written by very experienced IBM professionals from all over the world. They are written at the International Technical Support Organization (ITSO), which has centers close to IBM's development divisions.

Redpieces are redbooks that are not yet published or have recently been published specifically for the web.

Redbooks can be ordered from IBM. Recently, IBM began publishing them on the WWW. To order, view or just check them out, the following link will take you there. http://www.redbooks.ibm.com/
