I guess your right about the virtual machine thing.  I just meant 
that it
would be a way to allow a program to be compiled using the specific
instruction set's schema, and in that manner would have something 
like a
virtual machine, in that it converts/compiles (whatever) the program 
to
binary when it's run.  In that sense it there would be something akin 
to a
VM that does that for you for an XPL program when it's first run.

Yeah, I know nothing about ISAs and compilers... so what?  Do you 
think the
people that made up ISAs knew about ISAs the first time they made a 
stupid
ISA?  Ya gotta start somewhere.

  "except compiled, but we don't have to compile it."  What does that
mean???  I hope that's a typo, Mr. Contradiction.
  Plus, it's nothing like a virtual machine.  You don't know anything 
about
compilers, or ISA, so keep your mouth shut dumb-ass!

    Why do you say that Richard?  Please explain.

      Boy Richard, that's a really stupid idea ....

        I was wondering if it really would be possible to make a 
schema to
describe
        an ISA in XML and use that during construction of a compiler 
for
XPL, that
        can map XPL code to the ISA for a specific processor?  Then if
another ISA
        comes along, we can use XSLT to map the ISA to the XPL 
compiler
specifically
        based on the new ISA's schema?  Any thoughts?  Am I totally 
off base
here?
        Perhaps this is something like a Virtual Machine, except 
compiled,
but we
        don't have to compile it.

        In addition, couldn't we use the same kind of technique for 
building
an XPL
        I/O library, which maps perfectly to the instruction sets 
dealing
with I/O?
        Maybe this is nonsense ... don't worry, just tell me, I have 
no real
idea if
        it would work - it won't hurt my feelings. :-)
