Apparently, there's enough of an Ada market for someone to be offering alternatives to Ada! ----- Rolf Hemmerling Hannover, 29.05.96 Erderstr.31 D30451 Hannover Germany Tel.+49-(0)511-2102352 E-Mail: r.hemmerling@mail.dhd.de Rolf.Hemmerling@stud.uni-hannover.de International Homepage: http://www.stud.uni-hannover.de/~hemmerli Deutsche Homepage: http://www.germany.net/teilnehmer/100,69976 Subject: PEARL - a language for people interested in "realtime" computing There is an alternative to ADA available, a realtime language primarily used in Germany, called PEARL (Process and Experiment Automation Realtime Language). It is a child of Algol like Modula and Pascal, but with realtime language elements like "ALL 0.5 SEC ACTIVATE task", "WHEN interrupt RESUME task", "REQUEST semaphore". There is PEARL and the successor PEARL-90. There are several implementations by commercial companies and university institutes, which differ in the implementation level or language standard (BASIC PEARL, FULL PEARL, PEARL-90). There are a number of books out for PEARL in german language, but just one book in english language: Wulf Werum, Hans Windauer: Introduction to PEARL Vieweg Publishing, 3rd. edition, 1985 ISBN: 3-528-23590-X An unlimited shareware test version of "PEARL 90" by the software company WERUM is available in the ftp-server directory ftp://ftp.fh-bielefeld.de/pub/systems/linux/Pearl-90/ The company WERUM has special student and education (university/school) prices for their WERUM-PEARL versions for MSDOS (real mode) and another for OS/2 (16-bit). With the MSDOS version, You may do all the tricks You know from TURBO-PASCAL ! You just may not sell programs (source and binaries) without the shareware or the educational versions. You may also ask for a complete language manual "PEARL 90 Language Report, Jan 1992" (good for learning, in opposite to the ADA manual), directly from the software company. Usually the paper manual costs 50 DM, plus postage and packing, but maybe people situated outside Germany should beg for a free "electronic" version sent to You back by email: WERUM DV Systeme GmbH Erbstorfer Landstr. 14 D21337 L�neburg Germany Phone: +49-(0)4131-8900-0 email: pearl90@werum.de Another implementation of PEARL, called RTOS-PEARL, running on the ATARI-ST and many professional VMEbus boards is available from Institut f�r Regelungstechnik University of Hannover Appelstr. 11 D30167 Hannover Germany Phone: +49-(0)511-762-4512 This address above is the right one for contacts from universities ! The price is rather low in comparison to the WERUM prices ! Commercial distribution of these and other versions is done by IEP GBRmbH Bachstr. 1 D30167 Hannover Germany Phone: +49-(0)511-71 68 40 Fax: +49-(0)511-701 11 31 As far as I know, there is still no english documentation for RTOS-PEARL. I myself am the coordinator of the "PEARL pool" for "HEISE Verlag", a publishing company in Germany. The "PEARL pool" is a collection of public domain software and free software written in PEARL language or written for the operating system RTOS-UH (the runtime system for RTOS-PEARL). Usually this software is written by german people with comments and dialogs in **german** language. This software is distributed on 3 1/2 disks for money (and is therefore not available in the INTERNET). Nevertheless, the "PEARL pool" consists of free software contributions of hobbyists, students, engineers,... Currently, there are 22 disks (spring 1996), for 10 DM each, available, plus postage and packing, from eMedia GmbH Bissendorfer Strasse 8 D30625 Hannover Germany Phone: +49-(0)511-53 72 95 Fax: +49-(0)511-53 52 147 I don't get any money from sales ! The publishing company "HEISE Verlag" features RTOS-PEARL and the operating system RTOS-UH since 1985, especially the version for the ATARI-ST.
