open(unit=10,access='SEQUENTIAL')
       do I = 1,200
         write(10,*)I
       end do
       backspace(10)
       backspace(10)
       read(10,*)I
       print*,I
       end


gives a runtime error.  it should report "199", just like g77.

This is probably the reason why the NIST tests FM108 and FM411 are failing.
