Procedure Handles
Every external procedure that is in scope within an application has a handle that identifies the context of the procedure. Using a valid procedure handle, you can execute the internal procedures and procedure triggers of the specified external procedure from any other procedure in your application. This capability is especially useful with persistent procedures. Thus, you can encapsulate related functionality and make it available to your entire application.
You generally store procedure handle values in variables or fields defined with the HANDLE data type. For more on procedure handles and how to use them, see the information on procedures in Block Properties."
