below are all features built-in POV-Ray SDL
#declare MyArray = array[3][2]; // define dimensions
#declare MyArray[0][0] = 0; // fill content
#declare MyArray[0][1] = 1; // fill content
#declare MyArray[1][0] = 2; // fill content
#declare MyArray[1][1] = 3; // fill content
#declare MyArray[2][0] = 4; // fill content
#declare MyArray[2][1] = 5; // fill content
#declare Value = MyArray[1][0]; // get value from value
// refill content in loop;
#declare D1 = 0;
#while (D1 < dimension_size( MyArray , 1 ) )
#declare D2 = 0;
#while (D2 < dimension_size( MyArray , 2 ) )
#declare MyArray[D1][D2] = sin(D1+D2); // any value
#declare D2 = D2 + 1;
#end
#declare D1 = D1 + 1;
#end
// read content in loop;
#declare D1 = 0;
#while (D1 < dimension_size( MyArray , 1 ) )
#declare D2 = 0;
#while (D2 < dimension_size( MyArray , 2 ) )
#debug "MyArray["
#debug str(D1,0,0)
#debug ","
#debug str(D2,0,0)
#debug "]="
#debug str(MyArray[D1][D2],0,-1)
#debug "\n"
#declare D2 = D2 + 1;
#end
#declare D1 = D1 + 1;
#end
Apart from built-in features there is also standard include file called
"arrays.inc" with set of macros to operate on arrays. There is separate section
about it in documentation.

No need for it IMO.

--------------( oo )--------------
Ok thanks. I did it in an Other way but when I made experimentations with
arrays, I had error. I guess this is the Initialization of the array that I
did wrong. I read the Help files serval times, but I didn't noticed my bug.
It save me a lot of time, Thanks again ABX it is well appreciated.
I posted Images on the povray.binaries.images.
