dynamic linking
Process under OS/2, whereby resolution of external references within an application to modules in dynamic link libraries (DLLs) is deferred until load time or run time. This allows modification of modules contained in DLLs without the need to link-edit an application once more. Since DLLs are normally written as reentrant code, dynamic linking also allows multiple applications to use the same copy of a DLL in memory, thus reducing the storage requirements of OS/2 applications.
