Yeah.  That's due to "memory protection" problems.
If you execute:

2 block @

it crashes.  And since the simulator uses block
memory for words like "mem" and "memory"...well
it's bound to crash.  :(

Yeah.  I realized that was the next step.  Just
wondering if anyone had done that before me.
Anyway, I got the simulator running under
the Qemu distribution.  

The blocks:

The Qemu image:

Now I'm back to the place I was before which is...
I have NO clue what to do once the sim is up and
running.

Oh, I've read the Chuck Moore papers on the subject.

And I can run the simulator (by loading block 42
in the Qemu version I made).  I see the register
display on the screen.  I can "step" ok.  But
that's about it.  So do I edit x18 code in a
regular ColorForth block, load it and "execute"
it?  Just not sure what to do.  It would be nice
if someone with a little more experience gave
a few screen shots of a x18 (or 25x) edit - 
compile - execute session.
