Whoops! In digging through my old notes on this subject
I see that it was really Peter Mason who first reported
this to us about a year ago. My apologies to Peter,
along with my thanks to both Peter and Wayne for their
(apparently vain) attempt to keep us all up to date.

Cheers,

David

P.S. Just for the record, on Windows machines reading
binary data, the EOF function can cause weird file pointer
errors. The work-around is to add the /BINARY keyword to
the OPENR statement.
