DIGITAL is being created using DataPerfect 2.6F - a remarkably powerful, versatile, robust and elegant remarkable DOS-based relational database that was released in 1985 as a key element of the WordPerfect Library - a library that included WordPerfect 3.0, and a powerful menu driven Shell program that allows rapid switching and data exchange between Shell-compatible programs.

The use of WordPerfect Shell 4.0 - the latest version - is integral to the design and development of the DIGITAL database, for example through the use of Shell macros that can, for example, automatically generate a set of data fields and set up formulas that define the field values; through the screen capture feature that is invaluable in documentation of the database; and enable full integration with WordPerfect 5.1+ - the still unrivalled classic of word-processing software.

ENGINE incorporated the ACCENTS and FORMULA databases along with additional panels for the various elements of the design of DataPerfect with the goal of portraying DataPerfect through the relational database of its elements, and to generate an open source curriculum in the DataPerfect Digital Engine in HTML format.

In the final stages before being given back its earlier name its DPManual, with a barely perceptible change in case - ENGINE, together with Digital Engine, Mark II - now MyPalace - and LIGHT, was host to initial implementation of information ecology panel and field name conventions, and to new panels imported from WordPerfect 5.1+ style and macro libraries - OPEN-03.STY and OPEN respectively - and to systematic harvesting of screen shots from help screens for Office Shell 4.0 and Office Editor 3.1 and a few from wp5.1+ in preparation for enhancement of the manual's coverage of these incorporating manuals in the cluster of programs whose design incorporates a common framework and interoperable features.

The final stage of this initial phase of ENGINE's life also saw the development of an expanded menu, and preparation for the creation of exception fields with corresponding indexes to provide menu access constrained to particular features or areas of interest.
