Ah thanks, I had wondered if there was a traditional approach.  But was
there a similar situation with blocks from the very beginning?  You'd
LOAD an initialization block for your application, which in turn would
use LOAD and THRU, maybe nested through multiple levels, to load the
rest of your program as e.g. a tree of subsystems.

Thanks, the above is helpful.

I didn't know about this restriction.  It's not mentioned in
Docs-html/Forth-source-files.html for gforth 0.7.0 or 0.7.9 at the
moment fwiw.  It sounds inconvenient.
