本文介绍了如何在Fortran中确保数据元素的自然对齐，特别是在实现DLL时。通过设置Fortran Data编译器选项中的Common Element Alignment和Structure Element Alignment，可以调整对齐方式。同时，对于Alpha系统，需要指定Thread Access Granularity以确保多线程安全的数据访问粒度。

三、几个说明的问题：

1． DLL 与EXE 的目录问题。

原始的Help中是如此说的：

For an application to access your DLL, it must be located in a directory on the search path or in the same directory as the main project. If you have more than one program accessing your DLL, you can keep it in a convenient directory identified in the environment path. If you have several DLLs, you can place them all in the same directory to avoid adding numerous directories to the path specification.

When changing your path specification on a Windows 95 or Windows 98 system, you must restart the operating system for the change to take effect. On a Windows N
