Yes, I've seen the demo.  But using the very screen you are working on as a
temporary workspace is hardly optimum.  It works in your demo because there
is nothing else of importance on screen and you are thus free to issue a CS
within your first repeat 8[ statement that is reponsible for getting the
numbers cut into the appropriate bitmap indices.

True.  But when you load a bitmap with the BITLOAD command it does indeed
show the bitmap on screen where the current turtle is.  At least, I've not
been able to do this differently.  And, as I've said above, this is just
not optimum.  What is needed is a method of mapping a bitmap onto a turtle
that doesn't involve destroying the current screen, or at the very least,
that doesn't involve the inefficiency of actually trying to load it by
displaying it first on screen and then cutting it away.

Am I still missing a way to accomplish this?

Many thanks for the feedback,
