PowerBuilder函数详解

都是经常用到的函数

• 　　LowerBound()

LowerBound()功能得到指定数组第n维的下界。

语法LowerBound ( array {, n } )

参数array：数组名n：数值类型，可选项，指定要得到数组哪一维的下界。缺省值为1返回值Long。函数执行成功时返回array数组第n维的下界。如果n的值超过了指定数组的最大维数，那么该函数返回-1。如果任何参数的值为NULL，LowerBound()函数返回NULL。

-Detailed PowerBuilder functions are frequently used functions •　LowerBound () LowerBound () functions are specified in the first n-lower bound of the array. Syntax LowerBound (array {, n}) parameter array: the array name n: numeric types, options, which specify the dimensions to get the lower bound of the array. The default return value is a Long. Function is executed, returns the first n-dimensional array lower bound of the array. If the n value exceeds the maximum specified array dimension, then the function returns-1. If any parameter is NULL, LowerBound () function returns NULL.
