I don't see the need myself, I do see how it allows the 'Something' sub to vary what sub it calls by varying the 'test' parameter passed in, but I question the need and wonder, since 'test, could be varied, if that need could be fulfilled another way by select or if within 'Something. Of course I don't know the contet of your application, only what we have as an example... not much to go on.
