I would suspect the OPEN statement before I suspected the
structure in the ASSOC command. But you are right, it shouldn't
crash. Probably a bug somewhere. If you have a small reproducible
program, send it to RSI and find out.

I don't think this is true. In any case, it is WAY to early
to jump to this conclusion. :-)

Store the filenames and just do the ASSOC whenever you need something
from the file.
