3 - Final Steps Tree

The First Step

                Define New Window ( win1 ) , Title : "Draw Gradient"

                                Window Events

                                                Event: ON INIT : Action mydraw

                                Window Properties

                                Window Controls

                                End Of Window

                                Activate window

Procedure

                Define Procedure mydraw

                                Start Here

                                                FOR LOOP ( From x = 1 To 255 Step 1)

                                                                Start Here

                                                                                Draw Line AT x,x TO x,200

                                                                                y = 256-x

                                                                                Draw Line AT y,y+255 TO y,455
