The canonical answer has tended to be

x=random(seed)%500

Where % returns the modulus (remainder) after dividing by 500.

Seed is usually pulled from the system clock or keyboard timer or
whatever.

On the other hand, this is probably a non-runtime-speed-optimal way of
generating random numbers...you could generate a look-up table during
initialization, maybe...
