A quick reference to the Inform programming language.
A property variable inherited from an object's class is
addressed by *object.class::property*; this gives the
original value prior to any changes within the object.
+
+Manipulating the object tree
+----------------------------
+
+To change object relationships at run-time:
+
+ move object to parent_object ;
+ remove object ;
+
+To return the parent of an object (or nothing):
+
+ parent(object)
+
+To return the first child of an object (or nothing):
+
+ child(object)
+
+To return the adjacent child of an object's parent (or nothing):
+
+ sibling(object)
+
+To return the number of child objects directly below an object:
+
+ children(object)
+
+Message passing
+---------------
+
+To a class:
+
+ class.remaining()
+ class.create()
+ class.destroy(object)
+ class.recreate(object)
+ class.copy(to_object,from_object)
+
+To an object:
+
+ object.property(a1,a2, ... a7)
+
+To a routine:
+
+ routine.call(a1,a2, ... a7)
+
+To a string:
+
+ string.print()
+ string.print_to_array(array)
