变量的共享

标识符extype跟C语言中的extern标识符具有对应的特性。在定义和引用的部分中的一致性。

声明格式：

EXTERNDEF [[langtype]] name:type [[, [[langtype]] name:type]]...

MSDN Remars:

If a name exists in the module, it will be considered as PUBLIC. If a name is referenced within the module scope, its visibility will be set to EXTERN. If a variable or constant isn't referenced elsewhere in the program, it will be removed during compilation. The type specifier ABS can import a variable by reference without creating a new one. Such declarations are typically found in include files.
