fortran - error message in plato -


i new fortran , doing elementary practice. have installed plato latest edition. found program in net, , try compile 

program dotprod   implicit none   real :: c   real, dimension(3) :: a, b   print*,'enter first vector'   read*,   print*,'enter second vector'   read*, b   c = a(1)*b(1) + a(2)*b(2) + a(3)*b(3)   print*,'dot product = ', c  end program dotprod

plato shows no sign of error when build , compile, when try run program following error message shows up: executable not exist.

can me explain how handle error ?

thanks
