Pixel coordinates
— Refer to the pixels that physically make up the screen. These
are independent of the viewing window because the screen is always:
239 (0 to 238) pixels wide and 103 (0 to 102) pixels tall.
•
Point coordinates
— Refer to the coordinates in effect for the current viewing window
(as defined in the Window Editor).
Note:
For information about pixel coordinates in split screens, refer to the
Data/Matrix
Editor
module.
Many drawing commands have two forms: one for pixel coordinates and one for point
coordinates.
Note:
Pixel commands start with
Pxl
, such as
PxlChg
.
