clc - Clear Command Window
clc() clears all input and output from the Command Window.
After using clc() , you cannot use the scroll bar to see the history of functions, but still can use the up arrow to recall statements from the command history.
clc(nblines) clears nblines above cursor current line and move cursor up to this line.
Note that clc([nblines]) cannot be used under Unix/Linux platforms when Scilab used in no window mode.
