I wonder whether I could get some feedback on the following problems.

I have a few lines of codes to create an object, use it, and release it later.

o1 = createobject("my_object")
......

oCurrent = o1
... do something with oCurrent ....

o1.next = createobject("my_object")
oCurrent = o1.next
... do somethig with oCurrent ....

&& now I try to release to objects
release oCurrent
release o1

My questions are:
1. does oCurrent = o1.next copy the object or just the reference of the object?

2. does release oCurrent release the memory acquired in 2nd createobject?

3. does release o1 release the memory for both createobject(...) even without the release oCurrent?
