Hello, Ryan & Christopher:
Thanks to you both, for your ideas.

Not on its own - I tried it "as is", after getting variable names synced, but
it didn't work. Having said that, I didn't pursue it, to find out >why< it
didn't work for me.
The following is what I ended up using:
; get top drawer-list
drawer-list: READ read-drawer
cur-files: COPY 
all-files: COPY 
; append each directory list into block
FOREACH drawer drawer-list [
new-path: JOIN read-drawer drawer
cur-files: READ %.
all-files: APPEND all-files cur-files
It reads the top drawer, for that drawer's list of directories, builds a new
path for each sub-directory (there's only one sub level), changes its local
path, then reads each sub-directory, appending its file names into a block.
It's not smart, in the sense that it only deals with directories, but it does
what I need, for now. A file in the top drawer will stop the run, though, so
it most definitely can be improved. Making it into a function may be the next
step, but I'll use it this way, for a while, first.
