::summary Simulation language ::

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{{cite book |title=Simulation With Arena |isbn=978-1467273411 |url=https://books.google.com/books?isbn=1467273414 |date=2016 |quote=SIMSCRIPT … was implemented as a Fortran preprocessor on the IBM 7090 |first=W. |last=Kelton |title=The Development of the SIMULA Languages |url=https://hannemyr.com/cache/knojd_acm78.pdf |quote=The development of … SIMULA I and SIMULA 67 … were influenced by the design of SIMSCRIPT … |author=Kristen Nygaard |date=1978}}

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{{cite web |title=The SIMSCRIPT III Programming Language for Modular Object … |url=https://www.caciasl.com/docs/SIMSCRIPT_III_Paper_Win_Sim.pdf |author=M.

: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.

By 1997, SIMSCRIPT III already had a GUI interface to its compiler.{{cite web |date=June 26, 1997 |url=https://www.simscript.com/cust_center/sim3r2docs/SIMSCRIPTIII_User_Manual.pdf |title=SIMSCRIPT III User's Manual |archive-url=https://web.archive.org/web/20201124183456/http://www.simscript.com/cust_center/sim3r2docs/SIMSCRIPTIII_User_Manual.pdf |archivedate=2020-11-24}} The latest version is Release 5; earlier versions already supported 64-bit processing.{{cite web |title=CACI Products |accessdate=March 12, 2019 |url=https://www.simscript.com/downloads/downloads.html}}

PL/I implementation

A PL/I implementation was developed during 1968–1969, based on the public domain version released by RAND Corporation.{{cite book |title=Encyclopedia of Computer Science and Technology: Volume 13 |url=https://books.google.com/books?isbn=0824722639 |isbn=978-0824722630 |author1=Jack Belzer |author2=Albert G.
