HOW TO GRADUALLY CLEAR A BLACK SCREEN ?

First you must configure the screen : you must write these commands:
:Clrdraw...............To clear the screen
:Axesoff................To disable axes
:1->Xmin
:64->Xmax
:1->Ymin
:96->Ymax............To configure the screen

Then you must use the for command to clear a line (in fact, to trace a white line) which will have an variable Yvalue.
:For(A,1,64)......................The A value will start at 1, and will finish at 64
:Line(1,A,96,A,0)..............To clear a line which has a Xvalue of 96 and an Yvalue of A
:End..................................To stop the loop.
