If you are using a free version of Rexx you might have met the owner of that version. The Symposium fee covers the tutorials presented by professionals - people who have a career teaching Rexx, or who teach it to university students that are studying other disciplines. Some people are lucky enough to program as a hobby and it is no surprise that they choose to program in Rexx or even to implement Rexx. Over the last three years we have heard all about the internals of Compact Rexx - the smallest and fastest Rexx implementation yet. Maybe you thought some intricate programming deep in the system was needed to get these effects.
Some tasks sound too hard to contemplate.
At the Symposium we heard that with Rexx to help it isn't impossible, although it does mean garnering information from the dark corners of the Microsoft Developers Network. With automated control of the Registry comes the potential for groups of PC's which have any differences between them brought about by design rather than accident. The farmers don't have computers, the big company relies on computers. The application in between must guide the farmers to input data over the telephone, dynamically interpreting the noises from the phone touch pad and choosing the right messages for each step. Not with Rexx to help.
