Comments

The reason I provided a cursor was for the text support. When you turn the cursor on it acts exactly like the cursor you have in text screen mode. It advances 8 points at time up and down so it will always cover a text character evenly. One example of using the text cursor is if you develop an input routine. You could turn the cursor on to show the current position where the person was typing. You could use the half cursor size to indicate the person had pressed the insert key and now the insert state is active.
