Thanks, Robert! That's exactly what I was trying to accomplish, but I was
trying to do it all at compile-time.

Hot diggety! I'm about to write a chess program in Genie! :-)


Here's Robert's example translated from Vala to Genie:

[indent=4]
//int [,] arr;
arr : array of int[,]  // declare array name with global scope

//public void main(string [] args) {
init
    //arr = new int[3,4];
    arr = new array of int[3,4]  // allocate the array
    arr[0,0] = 1;  // initialize it
    arr[1,1] = 2;
    stderr.printf("%d:%d\n", arr[0,0], arr[1,1]); // print it
//}



I want to make certain I am understanding this correctly:

1. All multi-dimensional arrays in Vala/Genie *must* be allocated at 
run-time,
   not at compile-time

2. Optionally, the multi-dimensional array name can be declared a global 
name


Is this correct?
