SIMSCRIPT was originally implemented as a FORTRAN pre-processor. It required coding forms. SIMSCRIPT I.5 was developed in 1964 by Markowitz, Kleine, and Russell at CACI. A SIMSCRIPT I.5 compiler was developed to compile SIMSCRIPT I.5 source code into machine object code. SIMSCRIPT II was derived by Markowitz, Kiviat, and Villanueva at RAND in 1968. It eliminated the coding forms and created an English-like free-form language. SIMSCRIPT II Plus was created by Kiviat, Kleine, and Villanueva at Simulation Associates in 1969. It was SIMSCRIPT II with language additions and performance improvements. SIMSCRIPT II.5 was developed by Markowitz, Johnson, Delfosse, and Russell at CACI in 1971. It was SIMSCRIPT II Plus with all the unimplemented features fully implemented. CACI in La Jolla, California has continued to support and enhance this version. The genius behind SIMSCRIPT is Harry Markowitz, co- founder of CACI and recently the winner of a Nobel Prize in Economics. Present Status of SIMSCRIPT II.5 SIMSCRIPT II.5 is fully supported by CACI and in use by 4,312 organizations world-wide. Recent new users include: Air Canada, CERN, IBM, Port of Singapore Authority, NASA, FAA, AT&T, Hexale, UNISYS, Telesat Mobile, SAIC, British Aerospace, U.S. Army Corps of Engineers, Teledyne, Motorola, Duke Power, JPL, Lockheed, E-Systems, IEX, and ITT Aerospace. Currently, SIMSCRIPT II.5 is available on the following machines: Apollo MIPS ATT 3B2 PC DOS CRAY-2 PC OS/2 CRAY X-MP PC UNIX (386, 486) CRAY Y-MP Prime Data General AViiON Silicon Graphics IRIS DECstation SUN-3 ELXSI SUN-4 Gould UTX SPARCstation HP 9000/300 & 800 SUN 386i IBM 370 Tektronix 4300, 8800 IBM RS 6000 VAXstation MAC II VAX Training courses are held regularly by CACI in Washington D.C., La Jolla, and London. In 1990 alone, 540 students were trained in SIMSCRIPT II.5. In addition to CACI training, 750 university professors use SIMSCRIPT II.5 in their teaching through a special CACI program called SIMSTRUCTOR. A major recent enhancement, SIMGRAPHICS, allows SIMSCRIPT II.5 users to design menus, presentation graphics, and animated icons with no programming. It is standard with all PC and workstation implementations of SIMSCRIPT II.5. SIMSCRIPT II.5 with SIMGRAPHICS is completely portable over the range of machines supported. Compiled SIMSCRIPT II.5 executable versions of your models may be distributed to end-users with no royalty payments or run-time license fees. A 160 page catalog, Major Applications of SIMSCRIPT II.5 with SIMGRAPHICS, is available free of charge. Contact Doug Dittrich at CACI Products Company by phone (619) 457-9681 or by FAX (619) 457-1184. Planned Enhancements for SIMSCRIPT II.5 CACI is committed to the on-going enhancement of SIMSCRIPT II.5. Extensive advancements are scheduled for release at the Annual Simulation Conference in La Jolla on August 20-22, 1991. A new SIMSCRIPT II.5 based simulation system will be unveiled. The environment consists of: an interactive programming environment - SimLab, a symbolic debugger - SimDebug, a simulation database with SQL interface - SimBase, a complete input and output graphics package - SIMGRAPHICS, and a VCR-like graphics playback utility - SimVideo. For further information on the free trial of SIMSCRIPT II.5, please contact Doug Dittrich at CACI Products Company by phone (619) 457-9681 or by FAX (619) 457-1184. ------------------------------ Newsgroups: comp.simulation Path: tigger!ralex From: ralex@boulder.Colorado.EDU (Repenning Alexander) Subject: Simulation in Common Lisp Originator: ralex@tigger Keywords: simulation, Common Lisp, CLOS, DEVS Sender: news@csn.org Nntp-Posting-Host: tigger.colorado.edu Organization: University of Colorado, Boulder Date: Tue, 8 Jan 1991 20:36:46 GMT I'm interested in efforts undertaken in simulation based on Common Lisp / CLOS. Especially discrete event simulations are of concern (e.g., Zeigler's DEVS). I'm not looking for a commercial system; any hack or any reference to a hack will do (a public domain hack that is). I've posted a request like this before to comp.lang.lisp. As a result I got a lot of email of people sharing my interest but no one could give me helpfull hint. Is this really possible; is there no such system? Why could that be? Is Common Lisp inherently bad for simulation? Is CL too slow? Are other Lisp dialects more desireable (e.g., Scheme)? Why?..

If you have been considering a technical posting that does not belong in your newsgroup, or if a topic under discussion is in need of cross-disciplinary expertise, it is possible that folks in sci.engr will be interested. Here's the group charter: (1) To examine engineering problems in academia and industry, and the approaches taken in solving them; (2) To discuss tools used by the engineer (e.g. software, mechanisms, algorithms, strategies, etc.); (3) To exchange information relevant to the accomplishment of engineering tasks. And here are a couple of potential side benefits: (1) A place to establish traffic, leading, if possible, to an engineering hierarchy someday (sci.engr.chem has already been spawned); (2) A clearing-house of disciplinary experience that can be applied in other sci groups.

Vizzier Jr.) To: simulation@bikini.cis.ufl.edu Subject: WANTED: Information on Thermal Analysis Systems I am currently interested in finding out what is available for thermal analysis/simulation/modelling. This request has two parts: 1) I am interested in thermal analysis packages that allow simulation of computer components (ICs and PC boards on a mother board and/or backplane). We are looking for a system to model the thermal aspects of computers that are used to control experiments on shuttle flights. 2) I am interested in general thermal analysis packages for conduction, convection and/or radiation. Examples of these packages are SINDA and TRASYS. This request is simply due to supporting the thermal engineering group at Marshall Space Flight Center, AL and a desire to know what is available that we might not be aware of. In both cases both public domain and proprietary packages are of interest. If anyone else has an interest in thermal analysis systems, I would be happy to share the information that I collect. --- Ben Vizzier, Jr. Boeing Computer Support Services vizzier@turing.msfc.nasa.gov Ardmore Station, MS EC-00 (205)544-4363 P.O. box 5128 Huntsville, AL 35814-5128 ------------------------------ END OF SIMULATION DIGEST ************************
