WordPerfect Library (1998) 0 Utility Editor PIM DOS

WordPerfect Library, introduced in 1986 and later renamed WordPerfect Office (not to be confused with Corel's Windows office suite of the same name), was a package of DOS network and stand-alone utility software for use with WordPerfect. The package included a DOS menu shell and file manager, whose macros allowed text to be moved from one program to another (for example, from WordPerfect to Calendar, and vice versa), a do-all editor, apparently that of Wordperfect 3.0, which could edit binary files as well as WordPerfect or Shell macros, calendar, and a general purpose flat file database program that could be used as the data file for a merge in WordPerfect and as a contact manager.
