Java's -=[SUPPOSED]=- to be the same, no matter the platform on which it runs.

However, you can't lock in a customer base that way, so...

-Microsoft has done strangely unique things to it, so much so that they're
not allowed to call it JAVA any more.

-IBM has done less strange things, but they've added, uh, 'classes,' I
believe they're called, that implement "extensions" that will only run on
the AS/400 (ie accessing Data Areas).

-I'm sure there are other vendors that have their 'extensions' as well.

If you use the 'vanilla' functions, your code should execute on any system
that supports JAVA.  If you want things that only the AS/400 supports, you
can use the extensions, with the realization that your code is now
restricted to "IBM AS/400 JAVA."
