Tandem Computers Inc yesterday unveiled the newest programming language for its NonStop systems, Tandem Ada, which has already been validated by the US Department of Defense Ada Joint Program Office for full compliance with the ANSI/MIL-STD-1815A and the companion ISO spec – but Ada is increasingly also being used in civilian applications in areas such as real-time control and factory automation. Four programming tools are provided with the Ada – a compiler, a library manager, a binder and a symbolic debugger. Tandem Ada supports big programs that can have up to 4Mb of instruction code and can manipulate up to 128Mb of data per single process within a NonStop system; it runs on all models. It is $20,900 plus $800 a month per system on the NonStop VLX, TXP and NonStop II, $10,475 and $400 a month on EXTs and CLXs, from the fourth quarter.
