HMG3 autorelease

[l3whmg]

Hi friends I need help to remember better HMG3 events to replicate the same on HMG4

I have a MAINFORM open with this settings:

• SET INTERACTIVECLOSE ON, AUTORELEASE ON, OnInteractiveClose is NIL, OnRelease is aaaaaaa()

I have a otherform (CHILD/STANDARD) open with this settings:

• SET INTERACTIVECLOSE ON, AUTORELEASE OFF, OnInteractiveClose is NIL, OnRelease is bbbbbbb()

IF I click upon [X] of otherform this form is hide: that's ok. The related OnRelease function bbbbbbb() is execute? I think NO

Now I click upon [X] of MAINFORM: what happens? Remember: otherform is hide
The Onrelease bbbbbbb() function related with otherform is execute?

Many thanks
Cheers
p.s. other question
I have a MAINFORM open with this settings:

• SET INTERACTIVECLOSE ON, AUTORELEASE ON, OnInteractiveClose is NIL, OnRelease is aaaaaaa()

I have a otherform (CHILD/STANDARD) open with this settings:

• SET INTERACTIVECLOSE ON, AUTORELEASE OFF, OnInteractiveClose is NIL, OnRelease is bbbbbbb()

The otherform is already hide.
Can I close the MAINFORM?
