RANDOMIZE Statement
RANDOMIZE Iseed!
The RANDOMIZE statement is used In conjunction with the
random number function (RND). When the RANDOMIZE
statement is not used, the random number function will generate
the same sequence of pseudo·random numbers each time the
program is run. When the RANDOMIZE statement is used without
a
seed, a different and unpredictable sequence of random numbers
is generated by the random number function each time the program
is run. If you use the RANDOMIZE statement with a seed
specified. then the sequence of random numbers generated by the
random number function depends upon the value of the seed It the
same seed is used each time the program is run, then the same
sequence of numbers is generated, If a different seed is used each
time the program is run,
then a different sequence of numbers is
generated. The seed may be any numeric expression. The number
actually used for the seed is the first two bytes of the internal
representation of the number. (See "Accuracy Information" in the
Appendix for a complete explanation.)
Thus, it is possible that
the same sequence of numbers may be generated even if you
specify different
seeds. For example. RANDOMIZE 1000 and
RANDOMIZE 1099 produce the same first two bytes internally
and thus the same sequence of numbers If the seed you specify is
not an integer. then the value used is INT (seed) (see ·'INT·
Integer").
