Details
Shifts cursor position or display to the right
or left without writing or reading display
data. This function positions the cursor in order to modify an individual character, or to scroll the display window left or right to reveal additional data stored in the DD RAM, beyond the 16th character on a line. In a 2-line display,
the cursor moves to the 2nd line when it passes
the 40th digit of the 1st line. Notice that the
1st and 2nd line displays will shift at the
same time. When the displayed data is shifted
repeatedly each line only moves horizontally.
The 2nd line display does not shift into the
1st line position.
