This note describes XyWrite III+ in some detail, with emphasis on (a) its overall architecture and on "internals," and (b) its "macro"/programming/automation facilities. The target audience is threefold: (1) XyWrite III+ users who want more understanding, mostly of XyWrite XPL programming, (2) others who have never used XyWrite, and "wonder what the fuss is/was all about," and (3) myself -- since nothing clarifies one's thoughts about a given topic as trying to explain the topic to someone else. //

XyWrite III+ is a product that many users still feel is the best writing tool they have ever experienced. But, due to some misestimation by XyQuest (XyWrite's developer) as to how much MS Windows would damage the DOS applications market, plus an untimely, misguided, and costly partnership between XyQuest and IBM at about the time Windows was emerging, XyQuest failed at about the time MS Windows emerged. XyWrite development largely ceased soon thereafter.

In my view, many of the concepts that made XyWrite great have never been articulated, and many of them died when XyQuest died. This note attempts to explore and lay out some of those concepts, in a way that they might be appreciated even by someone who has never used the product, in the hope that some of these concepts might emerge in some measure in future "word processing" software. This hope, however, is perhaps a rather slim one -- nothing will make a person into a XyWrite fan as much as actually using the product will.
