'-----------Graphics Tutorial--------------
'
'To do graphics, you must have the screen in a mode for graphics.
'You basically have few different commands to use:
'
'LINE
'CIRCLE
'PSET
'PAINT
'
'------------Lines---------------
'When making a line you need to put in the X coordinate where you want the
'line to start, and the Y coordinate where you want it to start....Remember
'X is always be for Y, unless using the command LOCATE. The second set of
'numbers is the ending points. Let's say x = 50, and y = 100:
'ie. LINE (x,y)-(x + 10, y), c
'The c = the color that you want to use. after the c you can add a ", B"
'which turns the line into a box. Or you can put a ", BF" at the end,
'That makes a box, and fills it in with the same color.
'Let's try one.

CLS                             'Clears the Screen
SCREEN 13                       'Sets the screen to graphics
LINE (10, 10)-(100, 10), 4      'Starts at 10,10 and ends at 100,10, with the color red
LINE (10, 20)-(100, 50), 15, B  'Makes a box, with white
LINE (10, 60)-(100, 100), 1, BF 'Makes a filled in box, with blue
END                             'Ends this demo, remove this command to go on
                                'after you learn lines.

'------------CIRCLES-----------
'Circles are pretty easy. You just type CIRCLE (x coordinate, y coordinate), (radius)
'Like this: (x = 10, y = 10)
'ie. CIRCLE (x, y), (10)......the center of the circle is at x,y
'Lets try one.

CLS                              'Clears the screen
SCREEN 13                        'Set the graphics
CIRCLE (10, 10), (10), 4         'Puts the center of the circle on 10,10
                                 'Sets the radius at 10, and the color (4) at red
                                 'To fill in the circle, we use the simply
                                 'command PAINT
PAINT (10, 10), 4, 4             'The 4 is the color to fill with (red) and the
                                 'second 4 is the color to fill to (red)
END                              'Ends this demo, take this command out when
                                 'you have finished with circles.

'-------------PSET----------------
'PSETing is the simplest. It just places a pixel on the screen where ever you
'tell it to.
'ie. PSET (50,50),1
'The 50,50 is the place to put the pixel. The 1 is the color (blue)
'Lets try one:

CLS                               'Clears the screen
SCREEN 13                         'Sets the graphics
PSET (20, 20), 1                  'Puts a pixel (dot) at 20,20 and makes it
                                  'blue (1)
END                               'This ends the tutorial, but keep reading!
