Macintosh
These are declarations of global external functions for the functions in an export file on the Macintosh。
The arguments for the LIBRARY keyword (for example, PBSample1。dll) are fragment names, not shared library filenames。

声明为ref的为实参，既为传入值也为传出值

调用
函数名( 参数1,参数2)
有返回的变量
val = 函数名( 参数1,参数2)

PB中如何调用C#中的。
dll动态连接库，
C#中的代码如何写？
我是这样写的！
C#中：文件名ClassLibrary。dll
using System;
class MyClass
{
public int Main(out int i)
{
return i;
}
}
PB中：
定义 FUNCTION int Main(int i) Library "ClassLibrary。
dll "
事件中：
int c,d
d=Main(c)
MessageBox(string(d),strign(c))
错误提示：

PowerBuilder Application Execution Error (R0021)
---------------------------
Application terminated。
Error: Bad runtime function reference at line 2 in clicked event of object cb_1 of w_dll。
