>You can also always later migrate your VFP source code to other projects with very little revision, like Alaska Software's Xbase++, or Harbour's 32/64-bit compiler, even Lianja or other product, and prayerfully one day ... Visual FreePro. :-)

I don't think that is really an argument to start something from scratch in vfp. Why not start with the other project, if you see already a need to port ? Lianja is in Open beta and IMO workable enough to build something new if own dev will take some time. As the products you mention are similar enough in paradigm, a port can still be made.

@Luis: if you feel at home with the layered/tiered way vfp (according speakers or books for instance) apps should be written and like to utilize cursors for local data storage - look into Lianja. Other pricing model yes, but vfp pricing model killed vfp by not earning enough IMO.
You can program in the layered paradigma in a language following vfp (with smart enhancements) but can run on Win,Mac and Linux desktops and the Web. Android and iOS clients coming - but later - look at their roadmap.

If you like JS or Python (or [shudder] PHP), those interpreters are included in Lianja in addition to vfp-like language.
Might give you an option to start some routines with other languages (front end validation always in JS for instance, as browsers like it).

I have no monetary ties with Lianja or their company, although I helped a bit with some tools when I had some free time.
Hoping to earn a bit, if Lianja takes off by having come in very early: no secure bet - clearly a long shot compared to Java, C#.
But Lianja has already a lot of the benefits vfp had over Java and C# and growing more, newer, better ones. And is fun to play with - I have programmed in statically typed languages from Pascal, Modula2, C, Java and some C# - which I can fall back on if some small part needs more speed, but I generally prefer not to do all the code strictly typed.

>If you choose to go with something else, I would recommend Java. With Android gaining over 1.3 million new device activations per day world-wide, Java is not going anywhere. And, Java is open source.

Literally true. But Oracle is for me together with Apple at the bottom of my "like" list - I see Google and MS as less evil on Source code matters. If Luis wants a static typed language with memory managment, I think C# has grown beyond Java with dynamic and other enhancements - and Xamarin leverages most of the Open Sourced parts of Dotnet and might be easier to run on iOS than Java.
