...xSharp as Open Source feels much safer from the misgivings Victor and me share since vfp was abandoned - Lianja, Chen VfpA/Vfp64 and PCSoft all are closed source, MS is embracing Open Source for Dotnet more and more and xSharp sources are on GitHub.
Maybe Heinlein's TANSTAAFL applies to dev IDEs as much as it does to the rest of life! Personally I'm shelling out an annual VFPA support fee plus VFP C++ Compiler annual license that's worth every cent imho. Once enough of us are doing it and especially if we can convince experts like RH to aid the cause, we can have a product that compiles to C++ that's the most cross-platform option to this day if you think about it. (subtle hint)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
