Board Game Problem

Need help
I am creating a Blitz3d board game my problem is I need to throw the dice and move the player along the board, Ok I know how to throw the dice and hold the Dice number in a variable. But how do I check where I am on my Board. I have worked out all the positions
In X,Y,Z Variables that are possible for the players to move to, is there a way to say Postion_1 = X,Y,Z Postion_2 = X,Y;Z if this was possible then I could say
Player_1 =Position_1+Dice if Dice was say 4 THEN I could move the player to Position_5
If someone can help Code would be nice I have tried using Arrays[] did not work well
I got more in a knot and confused. Thanks

Personally I would use an array for this

; set up array for 11 positions (zero based)
Dim Position(10,2)

; Data x,y,z for each position
Data 10,0,10
data 12,0,10
data 14,0,10
data 16,0,10
data 16,0,12
data 16,0,14
... etc

; Read in positions
for n=0 to 10
read position(n,0),position(n,1),position(n,2)
next

to place a player at position 4 for example

positionentity player,position(4,0),position(4,1),position(4,2)

Maybe my explanation of Arrays on my programming website might be helpful...
