In Windows, a window can have maximize and minimize buttons depending on the settings of the MIN-BUTTON and MAX-BUTTON attributes. Both buttons are created on the window. If you set the MIN-BUTTON to TRUE and the MAX-BUTTON to FALSE, only the MIN-BUTTON is enabled; the MAX-BUTTON is disabled.
The MIN-BUTTON attribute must be set before the window is realized. The default value is TRUE.
On character platforms, this attribute has no effect.
