Hi, Charles,
I can more easily offer the fix rather than explain the problem. The short
answer is that REBOL needs the path. Try:
root: %/c/
sub: %rebol/
foreach file read full-path: join root sub [
if dir? join full-path file [print file]
]
(This sample is, of course, changed to something that I could run and show
the results.)
Hope this gets you past the hurdle, but I, too, would like to more fully
understand the distinction.
