National Instruments has released Version 5.0 of its LabVIEW graphical instrumentation software. Enhancements to the system include instrument wizards, ActiveX container, automation servers, translation and documentation tools, graphical differencing tools, programmable menu bars, and an undo function. A multithreading function boosts reliability and throughput, and allows the user to take advantage of multiprocessor machines. The software also includes tools that system developers can use to quickly and easily create distributed applications in which various sections of code can work on different machines across a network. Version 5.0 is available for Windows NT, 95 and 3.1; MacOS; Solaris; HP-UX; and Concurrent PowerMAX environments.
