Thanks much. This should keep me occupied and out of everyone's hair for a
while.

Write "my-arch make-image" in listener.
Then type Ctrl-W to walk it.
"Step" across my-arch
"Into" into make-image
Rinse, repeat. :)

the documentation. But perhaps you could save me five minutes.

Typically the architecture is a combination of os and arch:
IN: scratchpad my-arch . "unix-x86.64"
You can use the "my-arch" word to make an image for your architecture:
IN: scratchpad my-arch make-image

Thanks for the reference. I assume that will be helpful once I get past
stepping through the bootstrapping code and am in the Listener environment.

You might also find it useful to try the "Walker" which allows you to step
through Factor code:

If I'm understanding this correctly, you are suggesting that if I'm in the
Factor development environment, I can drop into Factor's own low-level
debugger. But what do people do (you language maintainer, for example) when
you need to debug the startup code that builds an image that needs to be in
place for the development environment even to be launched? Am I correctly
understanding you, that I can't use a Windows debugger to step through the init
sequence, but don't have Factor's debugger available yet either? Or am I
missing something?
Any insights would be greatly appreciated.
