Modify Position of particles in legacy system

Dear all,

Do you know if using the legacy system I could achieve positioning particles in space with their x,y,x coordinates, exactly as in shuriken?
If yes, do you have any sample code?
I need to create a galaxy map with stars.

PS: I cannot use Particle System as when I move the camera inside it, the particles dissapear with different camera angles… (the stars dissapear)


Sample code is right here:
