If I understand correctly after reading this thread, you want to use the lenses from your Nikon film camera on your upcoming Nikon digital, and the answer is generally "yes."
Nikon has maintained the same lens mount for years, at least for many SLRs (film and digital). Beware that it's a different lens mount from Canon and other manufacturers, so you generally can't use an older Nikon lens with a new Canon, for example.
Your experience may be different from mine. However, I can use a suburb old Nikon portrait lens (classic 105 mm) from my 25-year-old Nikon film camera on my Nikon digital camera. But of course most the automatic features on the camera don't work with the lens, since the lens was manufactured before the "digital age."
I use a Nikon D-80 with a Nikkor 18-200 mm lens. Hardly ever have to change lenses (and I don't like to, due to potential dust inside the camera and on its sensor).
Good luck into delving into digital photography!
