OK, I found what was wrong. I needed to insert:
IF INKEY(#path) =0 THEN blah, blah.
Remember that in OS-9/68K BASIC the INKEY routine returns the number of
chars waiting in the buffer, *not* the first key in the queue.
It appears that if you try to read from the buffer, and there's no waiting
chars, it seems to lock up.

It does ON ERROR GOTO, I dunno if CTRL-C is catchable, though.
