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.
