Is it possible that you could make available a sample SAS XPORT data
set that exhibits this behavior?  If so, please contact me privately
to arrange the transfer.

Saikat DebRoy and I were the people who wrote the foreign package but
neither of us has a whole lot of experience with SAS and we don't have
many sample data sets on which to test this package.

The problem is probably that the count of the rows in the data set is
too large by one.  Can you check the value from lookup.xport() and
compare it to the number of rows that should be in the data set?

The algorithm for determining the end of a data set in this format is
not well defined and apparently does not correspond to their
documentation.
