>Still the code is not portable yet. The point I was making, is that with your skills you could be a good programmer in any language you want. However you'll not be able to use your investment in code.

You can with Java, and eventually with any .Net apps because of portability readiness of CLR.

>If you've developed a framework in VFP, it's useless when moving to VB.net, C# or Java for that matter.
That's why I am a VFP.Net advocate for us to maximize our investment. With VFP's current status as a language and it's market acceptability, some VFP developers always feel insecure to some extent. Ofcourse I'm speaking only with those who are dependent with it. Linguist developers doesn't.

>Even if you're a Java developer, I doubt if your investment in code is 100% portable througout all Java versions on different platforms.

Sure it's not, because they've different color but almost the same capability. If it's English Language, a little difference between British and American accent.
