DECUS Heritage
Version: V3.07/0, June 1983
Submitted By: Maria Luisa Luvisetto, CNAF - INFN
Operating System: VAX/VMS
Source Language: VAX-11 FORTRAN
Keywords: Mathematical, Scientific Applications
Memory Requirements: 40KB
Abstract: ABACUS is a mathematical language that works as a parser-compiler-interpreter to enable computer users, both experts and not, in formula programming in a completely interactive way. Errors and results are displayed on a video terminal in machine-user dialogue. No previous knowledge of the computer is required. The language strictly follows the mathematical representation of formulas and guides the user where needed. For example, if a formula contains symbolic names, their numerical values are inquired by the program itself. The main elementary functions and second degree equation solution are provided together with constants such as PI. Temporary storage is at user disposal and plotting facilities are included. A set of the main unit conversions are built in. External file compilation with loop statements is provided to enable formula definitions of frequent use. All the above facilities provide a powerful tool for scientists, computer programmers, and technicians in computing and developing systems.
