SETWSIZE sets the size of a window. Its input is the name of the window to resize, and a list of two numbers: the width of the window in screen pixels and the window height. WSIZE reports the current window size. Note that this command changes the size of the window's outer bounds including its frame and the title bar; to change the size of  the drawing area of a window, use SETWINSIZE.

Change a window's position using SETPOS.
