PRINT @(x, y [, m]) expression
Same as the PRINT command except that the cursor is positioned at the coordinates x, y.
PRINT @(150, 45) "Hello World"
The @ function can be used anywhere in a print command.
PRINT @(150, 45) "Hello" @(150, 55) "World"
The @(x,y) function can be used to position the cursor anywhere on or off the screen. For example PRINT @(-10, 0) “Hello” will only show “llo” as the first two characters could not be shown because they were off the screen.
The @(x,y) function will automatically suppress the automatic line wrap normally performed when the cursor goes beyond the right screen margin.

m = 0 Normal text (white letters, black background)

m = 2 The video will be inverted (black letters, white background)
m = 5 Current pixels will be inverted (transparent background)
