I'm not sure I understand your question, but I'll take a shot at it. You can find out the dimensions of an array using ALEN(). ALEN(MyArray,1) will give you the number of rows in array MyArray, while ALEN(MyArray,2) will give you the number of columns. You can extend the size of the array using DECLARE or DIMENSION.
