A language for the simulation of the kinetic behavior of complex chemical or biochemical systems is described and defined. It is written in FORTRAN IV and should run on any medium or large size batch-processing computer (except that machines of short word-length will require double-precision arithme

✦ Synopsis
BIOSSIM is a revised and extended biochemical simulation language which has been rewritten in structured (machine-independent) FORTRAN to facilitate maintenance and modification. Its original capability to translate chemical reactions into differential equations and solve them has been greatly enhanced by provision to represent reactions at equilibrium and individual enzymes by primarily algebraic means, and by the capability to incorporate FORTRAN subroutines to modify or manipulate the solutions of the differential equations in order to more realistically represent physiological inputs to complex biological systems. Computational efficiency has been greatly enhanced by adaptation of the Gear stiff differential equation solver, which here runs effectively on computers of 32 bit wordlength, permitting minicomputer usage. Computational efficiency may be further improved by translating relatively small parts of the program into assembly language.
