Setting Many Pixels

If you want to make a longer program you can start with the above program and used the "Edit" menu and the mouse to "copy" and then "paste" copies of the PSET statement:

'SET A PIXEL AT (150, 32)
'
SCREEN 12
PSET (150, 32)
PSET (150, 32)
PSET (150, 32)
PSET (150, 32)
PSET (150, 32)
PSET (150, 32)
PSET (150, 32)
END

So far this is not an improvement, since the new program just sets the same pixel over and over. But now you can use the mouse to go to various characters, remove them with the delete key and then type in new values:

'NEW PROGRAM BASED ON THE OLD
'
SCREEN 12
PSET (150, 32)  ' set X = 150  Y = 32
PSET ( 50, 30)  ' set X =  50  Y = 30
PSET ( 75, 42)  
PSET ( 25, 72)  
PSET ( 10, 90)  
PSET (  0,  0)  
PSET ( 13,  5)  
END

The new program sets seven different pixels. Usually you do not set pixels one by one like this; better ways to draw pictures will be described later.
