# Randomize Statement

Initializes the random-number generator used by the Rnd function.

## āĻĒā§āĻ¯āĻžāĻ°āĻžāĻŽāĻŋāĻāĻžāĻ°:

Number: Any integer value. Used as seed to initialize the random-number generator. Equal seeds result in equal random-number sequences by the Rnd function. If the parameter is omitted, the Randomize statement will be ignored.

Unless a predictable sequence of numbers is desired, there is no need to use the Randomize statement, as the random-number generator will be initialized automatically at first use â it will be seeded using a system-provided random-number generator that produces uniformly-distributed, non-deterministic random numbers. If no such generator is available on the system, the system time will be used as seed.

The Randomize statement affects BASIC's Rnd function only. Other random-number generators (for example the Calc's RAND() function, etc.) are not affected by it.
