computer programming language similar toALGOL , but specialized for the development ofembedded system s.JOVIAL is an acronym for "Jules Own Version of the International Algorithmic Language." The "International Algorithmic Language" part of the name is from ALGOL, which was originally going to be called that (or IAL for short). It was developed to write software for the electronics of military aircraft by
Jules Schwartz in 1959. In the late 1970s and early 1980s, the U.S. Air Force adopted a standardized CPU, the1750A , and nowadays JOVIAL normally produces programs for that processor. JOVIAL was standardized in 1973 with MIL-STD-1589 and was revised in 1984 with MIL-STD-1589C. It is still widely used to update and maintain software on older military vehicles and aircraft. There are three dialects in common use: J3, J3B-2, and J73.As of 2006 , JOVIAL is still actively maintained and distributed by the [http://www.jovial.hill.af.mil/ USAF JOVIAL Integrated Tool Set (ITS) Program Office] , and a commercially supported [http://www.ddci.com/products_DJCS-t-MIL-STD-1750A/ JOVIAL Compiler System] is available from [http://www.ddci.com/services_software_migration3.php/ DDC-I] . The program office helps organizations reuse their old, reliable JOVIAL software by rehosting and retargeting the software to newer, more modern computer platforms and environments. The Jovial Program Office (JPO) is still active, as of 2007. JOVIAL rehosting and retargeting is currently done by [http://www.seadeo.com/ Software Engineering Associates, Inc. (SEA)] , [http://www.semdesigns.com/Products/MigrationTools/JOVIAL2C.html Semantic Designs, Inc.] , and [http://www.ddci.com/services_software_migration3.php/ DDC-I] .The current standard package (the "integrated tool set" or ITS) contains a compiler, a
MIL-STD-1750A assembler, linker, and simulator/debugger. It is available hosted from (runs on) either a DECVAX , SunSPARC , or a PC running DOS or Windows. Versions are also available that target (produce executable code for) theIntel 80386 (and derivatives), MIPS R4000,AP-101 , Zilog Z8002, andMotorola 68000 processors.Notable systems using JOVIAL include the Milstar Communications Satellite, Advanced Cruise Missile, B-52, B-2 bombers, C-130, C-141, and C-17
transport aircraft ,F-111 , F-15, F-16 (prior to Block 50), and F-117 fighter aircraft,LANTIRN , U-2 aircraft,E-3 Sentry AWACS aircraft, Special Operations Forces, Navy Aegis cruisers, Army Multiple Launch Rocket System (MLRS ), ArmyUH-60 Black Hawk helicopters, F100, F117, and F119jet engines , theNORAD air defense & control system (Hughes HME-5118ME system) and RL-10 rocket engines. Airborneradar systems with embedded JOVIAL software include theAPG-70 ,APG-71 andAPG-73 [ [https://wrc.navair-rdte.navy.mil/warfighter_enc/weapons/SensElec/RADAR/anapg73.htm AN/APG-73, Warfighter's Encyclopedia] ] .The
National Airspace System (NAS), the flight data processing program at the heart of the US and UK Air Traffic Control System, uses JOVIAL.References
