Java as a generic term.

Of course I know how it works, and probably java VM is closest, but I
wasn't speaking at that level.

Yes.

fwiw, there's a RPG .NET too.   (It's not called that, but it is
Visual RPG from asna I believe.)

   Does RPG compiled to jvm bytecodes have the same functionality as the
native RPG?  There are reasons that the jvm can not do well.  It has
limited data types and lacks support for constructs not in the java
language.

  Java generic.

  I know.

  Not really, and actually there's no reason it couldn't as I've seen an RPG
  compiler that spit out Java vm bytecode -- just nobody sees a need for
  multiple languages in the Java vm.

  I don't really count Java (vm) and .NET as competitors, they're designed
for
  different tasks and both do fairly well what they were designed for.

     java the language is supported by the .NET Framework along with C++,
C#,
  VB, and a host of others.  That sun's java the class library or sun's java
  the vm isn't well suited for other languages reflects poorly on it not the
  other languages.

    Agreed, but Java has the environment and C++ doesn't, and doesn't lend
    itself to that kind of environment either.
