The reason might be that row and column names you assigned are longer
than 8 chars, in which case lpx_write_mps generates dummy names like
RXXXXXXX and CXXXXXXX. If so, use lpx_write_freemps instead. It is
similar to lpx_write_mps, however, it writes the problem data in free
mps format which allows names of arbitrary length.
