Pete, Mike,
   I've put up a (slightly) more polished version.  Fixed up some typographical errors and improved (hopefully) the discussion of defining words.  I'm happy with it at this point.

Cheers,
Peter J.

A fresh version is up, using some of your suggestions.

I have to admit to not getting around to fixing the typos, yet.

Hi Peter,

Not sure I am able to see your new version yet.
Only found a few spelling typos in the original.

Here are 2 words I find very helpful exploring the usefulness of
FlashForth and PIC18 microcontrollers:

  : .mem  ( -- )          \ print current memory locations
     base @  hex
     cr ." flash  "  flash  here #4 u.r
     cr ." eeprom "  eeprom here #4 u.r
     cr ." ram    "  ram    here #4 u.r
     base !  ;

  : c?%  ( addr -- )                 \ print byte contents at addr in binary
     2 spaces base @ swap
     c@ 8 bin u.r
     base !  ;

c?% is useful to look at SFRs.

.mem is useful to examine further what Mikael was saying about FORGET vs
EMPTY .

          Side note:  I still prefer the original FORTH word COLD to
Mikael's EMPTY.

Don't leave out DUMP, especially when learning to create arrays and jump
tables.

Pete
