the next character to be displayed. The DKU91 0 I
uses the "bottom line entry" approach for the
display. The cursor moves only on the bottom
line of the display. The bottom line display
operates just like the print line of a journal roll,
i.e., a line feed causes the entire display page
(including the bottom line) to move up one line,
leaving the new bottom line blank, or clear. A line
return causes the cursor to move to the left
margin, at the first display position.

ously with another key causes repeated genera
