FIG. 3C is a flowchart showing the display routine. At n27, the currently displayed screen is cleared from the display 12, and the contents of the display number register DPN are determined (n28). The corresponding screen data is read from the screen memory 15 and displayed on the display 12 (n 29 ).

FIG. 3(D) is a flowchart showing the edit processing operation. In this operation, first, the edit flag EDT is set and it is determined whether or not there is an edit key event (n30, n31). If this condition is met, the operations proceed from n32 onwards. If this condition is not met, return directly. At rr 32, it is determined whether the turned-on key is a cursor key, +/- key, insert key, or delete key.

In the case of a cursor key, the cursor displayed on the screen is moved in response to the ON event of each of the cursor keys provided for up, down, left, and right (n33). If the key turned on is the +/- key, the contents of the registers that store the parameter currently displayed at the cursor position are increased by +1 corresponding to the + or - key being turned on.
