Creating Arrays创建数组
使用前必须先创建数组。说明数组的最大顺序（用赋值语句）。 大于最大顺序号时将出现run-time error 例如，先values[7] <- 3 则
1 0 2 0 3 0 4 0 5 0 6 0 7 3 如：values[9] <- 6 则： 1 0 2 0 3 0 4 0 5 0 6 0 7 3 8 0 9 6 对100个数组元素赋初始值0，可以：values[100] <- 0 Creating Two-Dimensional Arrays创建二维数组
numbers[3,4] <- 13。则二维数组 numbers 1 2 3
1 0 0 0 2 0 0 0 3 0 0 0 4 0 0 13 Array Operations数组操作
Length_Of
Length_Of is a function that takes one argument, a one-dimensional array without any index or square brackets after the name. It returns the highest index (which is also the number of elements) defined for the array. Length_Of can also be used to determine the length of a string expression.
例：Length_Of(Scores) will return 4.
