You can force a Object release ( not variable/property references )
with a
RELEASE this
or
Parent.RemoveObject

RefObject = CREATEOBJECT("someclass")
RefCopy   = m.RefObject

CLEAR

RELEASE RefObject
? RefCopy
RELEASE RefCopy

? "end"

RefObject = CREATEOBJECT("someclass")
RefCopy   = m.RefObject

* this set to null ALL the object references, and the object is destroyed
RefCopy.Release
? RefCopy
? RefObject
? "end2"

DEFINE CLASS someclass as Custom
	
	PROCEDURE Release
		RELEASE this
		
	PROCEDURE destroy
		? "destroyed"
		
ENDDEFINE
