It depends on what your need.
Sometimes what you need is reproducibility, and how much random are the
pseudo-random numbers is not very important.
Sometimes you need the contrary, usually for cryptographic reasons, and
you want pseudo-random numbers as much random as possible.
In gambas, you make the difference with the RANDOMIZE instruction that
intializes the pseudo-random numbers generator.
The same seed gives you the same numbers, so you achieve
reproducibility. At startup, the seed is initialized with the time of
Otherwise, either you directly use what is provided by the OS
('/dev/random' or '/dev/urandom') for maximum randomness, either you use
RANDOMIZE with the result of '/dev/(u)random' to get a random number serie.
