You port the byte code. It's along the lines of a compiles language. Every
JVM is supposed to be able to interpret these byte codes for its platform.
That's the basis of the 'write once, run anywhee' concept.

As far as data queues go, what the app gets is just data—it knows diddly
about DQ's. The Java class is imported into the app, and that's what knows
how to get to a DQ.

The bit about no AWT applies only to the AS/400, for now. There is no
implementation of AWT at the moment for the 400 green screen, although I've
sent the hint to the development team at Hursley to use green screen
replacements for the GUI paradigms, like subfiles for list boxes, etc.

As far as I know, I think.
