How are squawk codes assigned in tower cabs? I understand with the radar systems there is a function to do this (simulated with the F9 key in VRC/ASRC), but how would a clearance delivery controller, for instance, select a squawk code? Are there differences between newer towers and older towers in terms of the systems used to assign the codes?

FDIO.

FDIO.
Doesn't the NAS Computer have something to do with that as well as the FDIO?

Yes, the NAS assigns the codes which are released to each facility by the Center. The FDIO is simply the computer system used to link with the NAS.
