Can someone help me please? I have been working through the tutorials and have started playing around with the RND function but have come across something I am unsure about.

A=RND(100)
B=RND(7)

PRINT A, 100, 100
PRINT B, 120, 120
SHOWSCREEN
MOUSEWAIT

If I run this it generates the numbers 72 and 1. If I run it again it generates 100 and 0. If I run it a third time it goes back to 72 and 1 and a forth time 100 and 0, which doesn't seem very random, what am I doing wrong?

I wondered that but there is no mention of it in the tutorial.

Thanks, how stupid do I feel! Promise to stop bothering you now!

Sorry, it is from the tutorial.

// Project: One More

DIM playfield [10] [10]
level = 0

// Main game
main:
MOUSESTATE mx, my, b1, b2
PRINT "<=", mx, my-8
SHOWSCREEN
GOTO main
END

When I try to complie and run I get:

Ok So I spoke too soon! What does this mean?

Thanks guys, removing the tick in explicit declarations worked.

I am completely new to programming so please excuse me for being stupid. I have been working through the tutorials in the GLBasic manual, but i am having a problem. When I compile the program I get the error:  error : variable is not explicitly defined : bat_y
This is from the pong tutorial and I have even copied and pasted it to be certain I am not making a typing error.
DIM bat_y[2]
DIM bat_x[2]
DIM score[2]

Any help would be appreciated.
