It seems to me that...
All of your objects are cubes...
and they all are being positioned in the same place using the for/next loop.
You have given 'x' and 'z' a value, -99.
Then you position every object at...
x+11,y,z+11
So all objects are at...
-99+11, y, -99+11
And since they are all cubes...
It looks like just one cube.
When you do it individualy...
POSITION OBJECT 1,-99,-64,-99
POSITION OBJECT 2,-88,-64,-88
POSITION OBJECT 3,-77,-64,-77
POSITION OBJECT 4,-66,-64,-66
POSITION OBJECT 5,-55,-64,-55
POSITION OBJECT 6,-44,-64,-44
POSITION OBJECT 7,-33,-64,-33
POSITION OBJECT 8,-22,-64,-22
POSITION OBJECT 9,-11,-64,-11
POSITION OBJECT 10,0,-64,0
You have different values.
try...
for n=1 to 10
POSITION OBJECT n,((n-1)*11)+x,y,((n-1)*11)+z
next n
