what's wrong with DIm arrays? I mean, searching for the cube that has index 7...somewhat inefficient.
Graphics3D 800,600
cam=CreateCamera()
PositionEntity cam,0,0,10
light=CreateLight()

dim cube(199)
For i=0 To 199
 cube=createcube()
 positionentity cube(i),10,0,i*5
Next

While Not KeyHit(1)
 turnentity cube(7),0,.1,0
 RenderWorld()
 Flip
Wend


so...

cube(7)

replaces:

c.cube = first cube
counter = 0
repeat
counter = counter + 1
c = after c
if c.cube = null then runtimeerror("Does not exist")
until counter = 7
