RESIZE_FREELY

Normally, under a graphical host (such as Windows), the runtime will not allow you to resize an AUTO-RESIZE window larger than its logical size (as determined by the number of rows and columns the program requested when it created the window). When the RESIZE_FREELY variable is set to 1 (on, true, yes), the user can resize the window to any size. Maximizing the window will cause the window to occupy the entire available screen. The region of the window that lies outside of the logical area will not be accessible by the program and will be shown as the background color of the logical window (defined as the last background color to be applied to the entire window). Setting this option is essentially a cosmetic change to the way your application looks when maximized. The default value is 0 (off, false, no).
