This command creates a small job which blanks out the screen if a key has not been pressed for a specified number of minutes (default 5).
This command is useful, because if a very bright picture is drawn on screen (eg. a white line on black paper), and the screen does not alter, this can lead to what is known as ‘burn in’ when the monitor screen becomes permanently marked with the ‘ghost’ of the picture. This does not tend to happen very often nowadays, but in the past, monitors tended to become unuseable as more and more of their screen became covered with these ‘ghosts’.
This command will only work within the Pointer Environment.
BLS is a similar function under SERMouse.
