Hmm, well now my ignorance is exposed.  I didn't know that I had to deal with
both cell addresses and byte address--I assumed all addresses were byte
addresses.

I tried replacing "[ hw ] 13 type" with "[ hw 2* 2* ] 13 type", but now I just
get 13 garbage characters displayed on the screen.  I'll play around with it a
little more, now that I know I need to investigate the different address types.

FWIW, the '1@', 'string', and 'type' words that I'm using were copied from
blocks 42 and 48 of the patched colorForth available from my site.  I believe I
am using them the same way that they are used in those blocks.  I don't see any
adjustments being made for cell-vs.-byte issues.
