Lost in the Windows fun-house

>From my research on the Internet, it appears that it is possible to
dynamically switch a window from Normal to Modal or the reverse *in Linux*.
My question #1 is, is it possible to do this in Windows?

#2: If, as appears to be the case, in Windows you open a window as either
Normal or Modal, and it stays whichever way you chose until you close it
(which if it works that way is REALLY STUPID), how can I close a window as
Normal, reopen it as Modal, and when the user closes the Modal version, then
reopen it as Normal? All code sequences I have attempted so far fail to
produce the desired results. For example, this doesn't work:

procedure onClose_myWin()
  if myWin_isModal then
    myWin_isModal = False
    openWindow(myWin, Normal)
  else
    setFocus(parentWin)
  end if
end procedure

procedure toModal()
  closeWindow(myWin)
  myWin_isModal = True
  openWindow(myWin, Modal)
end procedure

Nor does this:

procedure toModalAndBack()
  closeWindow(myWin)
  myWin_isModal = True
  openWindow(myWin, Modal)
-- Assuming, perhaps erroneously, that control doesn't return here
-- until the modal window is closed:
  mWin_isModal = False
  openWindow(myWin, Normal)
end procedure

And question #3 would be, is the assumption indicated in the comment
correct, or does openWindow() spin off another thread of execution?

Puzzled in Windows-land,
George
