Int 15 Fn 12  - Topview - Send Message - "close" - Close Object            [Q]

   AH = 12h
   BH = 0Dh
   BL = object
       00h handle is DWORD on top of stack
       timer:    close
       keyboard: detach from window and discard queued input
       pointer:  stop taking input
       panel:    close
       mailbox:  close, unlock, and discard any pending messages
       02h close given task's mailbox (task's handle on top of stack)
       03h close task's default mailbox
       04h close KEYBOARD object (handle on top of stack)
       05h close task's default KEYBOARD
       06h close given task's OBJECTQ (task's handle on top of stack)
       07h close current task's OBJECTQ

Notes: when an OBJECTQ is closed, each object in the OBJECTQ is sent an
     ERASE message (AH=12h/BH=0Eh)
   when a panel object is closed, the panel file and any panels currently
     in use are freed; window and keyboard objects created by APPLY are
     not affected, but field mode input ceases
   open but idle timer objects consume a small amount of CPU time
