SIMSCRIPT

Source: Wikipedia, the free encyclopedia.

SIMSCRIPT is a free-form,

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.

SIMSCRIPT II.5

SIMSCRIPT II.5[5][6] was the last pre-PC incarnation of SIMSCRIPT, one of the oldest computer simulation languages. Although military contractor CACI released it in 1971, it still enjoys wide use in large-scale military and air-traffic control simulations.[7][8]

SIMSCRIPT II.5 is a powerful, free-form, English-like, general-purpose simulation programming language. It supports the application of software engineering principles, such as structured programming and modularity, which impart orderliness and manageability to simulation models.[9]

SIMSCRIPT III

SIMSCRIPT III

Object-oriented features.[12]

By 1997, SIMSCRIPT III already had a GUI interface to its compiler.[13] The latest version is Release 5; earlier versions already supported 64-bit processing.[14]

PL/I implementation

A PL/I implementation was developed during 1968–1969, based on the public domain version released by RAND corporation.[15]
