The commands "WF", "WH", and "WS" in the SCOPE debugger resize the height of the debugger window. The commands set the debugger window to the full ("WF") height, one half ("WH") height, or a quarter ("WS") height of the full screen, The debugger WINDOW command accepts a single numeric parameter to set the number of lines in the window (the command "WINDOW 6" or "W6" would select a height of 6 lines).
