Library Functions
SRAND
Synopsis
Description
The srand() function initializes the random number generator accessed by rand() with the given
seed. This provides a mechanism for varying the starting point of the pseudo-random sequence
yielded by rand(). On the Z80, a good place to get a truly random seed is from the refresh register.
Otherwise timing a response from the console will do, or just using the system time.
