FUNCTION: Fetches a random number, which may be the next in sequence, a repeat of the last one,
or the first in a new sequence. The RANDOMIZ E command in the above program ensures that RND
returns the same number each time
RND(0) returns a copy of the last random number generated. Where numeric expression1 is
negative, the number sequence generated is predictable.
