Re: RPG - I'm not dead yet!

Joe,

What i actually meant was, is that the OS/400 architecture is based on an
abstraction layer. Just like the JVM. So if you just run the JVM as any
other program (like it is on other platforms too), then the Java VM is
executed within another "VM", which is not efficient.

If you deploy a pure Java application (e.g. with websphere) the AS/400 is
not the most efficient.
A more "bare bones" OS like Linux is more efficient, simply because the JVM
is executed directly as machine code.

IBM had the chance, beginning of the 90's in the previous century, to
integrate smalltalk within the OS.
They had plans to do that.

Now we have a VM running on top of SLIC.
