The Window:full dimensions of a window include the work area, the border, and the margins. When creating a window in the Designer, or defining it in code with the window definition functions (wn_def(), wn_vdef(), wn_mfdef(), and wn_nbdef()), the window coordinates and row and column quantities refer to full window dimensions. This is the amount of space the window will take up on its destination screen. When a window's border or margins are changed, the window's full dimensions do not change. The size of the window's buffer also does not change. It is the area inside the frame, the interior work area where the user can see and scroll through the text, that is adjusted to match the new margins or borders.
