With a local variable, you need to declare the same variable every time for each new module or different sub-procedure. Hence, every time a new space is allocated for the pre-defined variable. Also, it makes the maintenance task quite cumbersome. The Global variable was introduced to prevent...

New可选。 允许隐式创建对象的关键字。 如果在声明对象变量时使用New,将会在首次引用该对象时创建一个新的对象实例,因此不必使用Set语句分配对象引用。New关键字不能用于声明任何固有数据类型的变量,并且不能用于声明相关对象的实例。 type可选。 变量的数据类型;可以是当前不支持的字节、布尔值、整数、长、货币、单...
