GRAPHIC WINDOW STABILIZE statement

Purpose | Make a graphic window stabilized (non-closeable).
Syntax | GRAPHIC WINDOW STABILIZE [hWin]
Remarks | The GRAPHIC WINDOW identified by the handle hWin is stabilized, meaning that it cannot be closed by the user. If there is a system menu, the close option and the close box are grayed. The ALT-F4 close key is disabled. This allows you to be certain that your operations on the graphic window can be completed. When a graphic window is stabilized, only GRAPHIC WINDOW END or program termination will close it.
