To reseed the random number generator.

Syntax

RANDOMIZE expression

RANDOMIZE TIMER

Comments

If the random number generator is not reseeded, the RND function returns the same sequence of random numbers each time the program is run.

To change the sequence of random numbers every time the program is run, place a RANDOMIZE statement at the beginning of the program, and change the argument with each run (see RND function).

RANDOMIZE expression will not force floating-point values to integer. expression may be any numeric formula.

RANDOMIZE TIMER 

Examples

The internal clock can be set at intervals.

RANDOMIZE TIMER
FOR I = 1 to 5
  PRINT RND;
NEXT I

The internal clock can be used for random number seed.

N = VAL(MID$(TIME$, 7, 2)) 'get seconds for seed
RANDOMIZE N                'install number
PRINT N                    'print seconds
PRINT RND                  'print random number generated
