110528 TAB: A Low-Overhead Data Management System for the PDP-11 Version: April 1984 Submitted by: R. N. Stillwell, Baylor College of Medicine, Houston, TX Operating System: IAS V3.1, RSX-11M V2.1 Source Language: FLECS, MACRO-11 Memory Required: 28KW Keywords: Data Base Management Abstract: This package builds a set of tasks providing a small, relatively unsophisticated data management system in which the user can easily define and manipulate tables of data. Tables are arrays of rows and columns containing data in character form. Tasks are provided to define a table, modify the format of an existing table, update and list the contents of a table, and split and merge tables. An interpreter for a simple language (RPT) provides a means of writing specific applications, including report generation and table updating. It has provision for arithmetic and string operations, terminal interaction, file I/O, conditional and repetitive execution, and subtasking. The 1984 release provides a full-screen table editor on VT100-compatible terminals, and all necessary modifications for FORTRAN 77 and RSX11M/M+ (including subtasking). Command and batch files for building and testing the package, and sources for the Flecs preprocessor are included. A spreadsheet application written in RPT is provided as an example. Media (Service Charge Code): 600' Magnetic Tape (MA) Format: DOS-11
