Description:
It is often possible to carry out lengthy and tedious but otherwise routine algebra involved in geophysical calculations on a computer. The technique yields confidence in the accuracy of the analysis and allows an approach to complex algebra which permits more attention to be paid to the broad principles of the problem and less to the details. FORMAC is a recent approach to the problem of manipulation of algebraic expressions. It is a preprocessor for PL1-like input to the IBM/360. An earlier version was a preprocessor for FORTRAN-like input to the IBM/7094. The language provides a group of commands which will manipulate symbolic expressions algebraically, differentiate these expressions and execute input and output for these expressions onto printers or direct access storage. Applications are made of FORMAC to several complex algebraic expressions which arise in geophysics. © 1968, The Seismological Society of Japan, The Volcanological Society of Japan, The Geodetic Society of Japan.
