SIMSCRIPT is a free-form, English-like general-purpose simulation language conceived by Harry Markowitz and Bernard Hausner at the RAND Corporation in 1962. It was implemented as a Fortran preprocessor on the IBM 7090[1] and was designed for large discrete event simulations. It influenced Simula.[2]
Though earlier versions were released into the public domain, SIMSCRIPT was commercialized by Markowitz's company, California Analysis Center, Inc. (CACI), which produced proprietary versions SIMSCRIPT I.5[3][4] and SIMSCRIPT II.5.
