Peter, thanks for the info. The IDL documentation certainly gives the
impression that the Windows-only /NOAUTOMODE and /BINARY keywords to OPEN
have an effect only when *writing* to a file. I guess my example shows
that one has to be aware of flipping between "text" mode and "binary"
mode, even when reading a existing file opened with OPENR.
