Knowing when not to use procedures

If you are writing an application that operates on a procedure in QMF temporary storage, you cannot write your application as a procedure. This is because, when you run a procedure, that procedure becomes the current procedure in QMF temporary storage.

For example, if you write your application as a procedure, and code your application to save the current procedure in QMF temporary storage, the application saves itself, because it is the current procedure in QMF temporary storage when it is running.
