Computers have a built-in list of random numbers. You can
get the same numbers by setting the computer to a place on this list.
To get real randomness, you have to set the computer to a random place on the list.
The computer keep the time since it was turned on. This is the one thing
that is really random.
So:
N=RND(-4) (You set the computer list with a negative number)
Sets the randomness list to the 4th place. Each time you write
this you get a list with he same numbers.
N=RND(-4) This says set the random list to the 4th place
X=1 TO 5 This says go into a loop 5 times
Y=RND(10) This says Y is a random number from 1 to 10
PRINT Y This says print the number
NEXT X This goes back and does the loop again
This program prints out 4 5 8 5 10 every time.
However:
N=RND(-TIME) This says set the random list to a random place. (The time on the timer.)
X=1 TO 5 This says go into a loop 5 times
Y=RND(10) This says Y is a random number from 1 to 10
PRINT Y This says print the number
NEXT X This goes back and does the loop again
Now each time you run the program, you get a different number list.
1 7 5 7 3
2 8 4 1 9
6 5 10 3 7
Putting in a randomizer line is necessary to get real random numbers.
It may be useful to have the same numbers at times; for example in a game
you may want the same numbers coming out for two players on different computers.
You can generate a player’s profile numbers without having to save them with his method too.
I was told, when running a bingo game, the organizers know the numbers called before time
to prevent disputes; they probably used this method.
