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.
