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.
