+A procedural type to a normal procedure or function is stored as a generic pointer,
|
|
|
+which stores the address of the entry point of the routine.
|
|
|
+
|
|
|
+In the case of a method procedural type, the storage consists of two pointers,
|
|
|
+the first being a pointer to the entry point of the method, and the second
|
|
|
+one being a pointer to \var{self} (the object instance).
