（1）定义整型多维数组类型，各维的下标是任意整数开始的连续整数；

（2）下标变量赋值，执行下标范围检查；

（3）同类型数组赋值；

（4）子数组赋值，例如，a[1..n]=a[2..n+1]；a[2..4][3..5]=b[1..3][2..4]；

（5）确定数组的大小。

-(1) the definition of multi-dimensional array of type integer, the dimension subscr ipt is any integer beginning in integers　(2) subscr ipt variable assignment, the implementation of subscr ipt range checks　(3) the same type of array assignment　(4) sub-array assignment, for example, a [1 .. n] = a [2 .. n+1]　a [2 .. 4] [3 .. 5] = b [1 .. 3] [2 .. 4]　(5) determine the size of the array.
