Abstract : The Omnidata system, consisting of 45 individual programs written in XBASIC, provides an interactive user-oriented facility for: data retrieval and report generation; plotting and other graphical analysis; arithmetic and statistical analysis; curve fitting and multiple analysis; author, title, and keyword indexing of bibliographic files; a variety of univariate analyses and two-way crosstabulations; and numerous utility modules for file definition, file updating, and file maintenance. The SEARCH module which performs a serial search through a file allows for: the usual Boolean operations; string searching on text fragments, stems, or roots in either the anchored or unanchored mode; specification of syntatical order and proximity of words or phrases, as well as variable length ellipsis; and ignoring one or more of a specified list of characters in its matching operation. Four of the modules interface with the OMNITAB II system for versatile plotting, very accurate least-squares fitting, and a comprehensive statistic al analysis. (Author)
