Manuscript Title: ABACUS: a natural language for the numerical computation of mathematical formulae.
Authors: M.L. Luvisetto, E. Ugolini
Program title: ABACUS
Catalogue identifier: ACFC_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 30(1983)277
Programming language: Fortran.
Computer: VAX 11-780.
Operating system: VMS.
Word size: 32
Keywords: General purpose, Utility.
Classification: 4.14.

Nature of problem:
The program allows interactive computation of mathematical formulae, iterative procedures and metric conversions.

Solution method:
Parsing of input string and use of basic mathematical functions as supported by the language itself.

Restrictions:
The limits are set to fit the mainly interactive use of the program.

Running time:
No running time measure is considered as the use is mainly interactive and the limit is set by the user himself, the result appearing on VT immediately after the input formula is typed.
