At Cyth we are fans of purchasing or using any product or feature that delivers quality results faster. It may be a hardware or software product, existing code, or a a hidden feature. Whether it's free, or if it costs $49 but saves 2 hours of time, we love productivity.
Shared variables are no exception. These features of a LabVIEW project allow us to define a variable and pass it between applications or between machines easily and with robust and reliable performance.
So use Shared Variables, experiment with them yourselves and see what you think!
