    Stein, Rose, and Parker [3] developed, in 1958, ASTRAL (Analog Schematic Translator to Algebraic Language) for the IBM 704 computer. In addition to being a significant advance in the syntax of simulation language, ASTRAL was written as a compiler which generated a FORTRAN program. Thus, FORTRAN was used as an intermediate language. ASTRAL also permitted the use of FORTRAN arithmetic statements in a certain specific manner. It introduced automatic sorting of the statements of a simulation program into a proper order; this feature makes preparation of a simulation program similar to wiring on the patch board of an analog computer.

    In 1958, M. L. Stein, J. Rose and D. B. Parker developed ASTRAL (Analog Schematic Translator to Algebraic Language) at Convair Astronautics. ASTRAL is a compiler that models the analog computer and generates a Fortran program as an intermediate step. The program can be modified prior to compiling and executing. Also ASTRAL provided sorting and centralized integration (Stein et al., 1959; Stein and Rose, 1960).
