SETTWINDOW
Syntax SETTWINDOW windowname
 
Explanation SETTWINDOW attaches all active turtles, controls, and bitmaps to a window. Its input is the name of the window in which those objects should appear. Using an empty list as the window name detaches all active objects from their windows, making them invisible.

Use the TWINDOW command to retrieve the name of the window of the first active turtle, control, or bitmap.
