(7) Shifting of data to the left during the input of a program
When the user inputs a program, the codes entered before a touch on the

key will appear on the 4th (bottom) line of the display area.
If the codes cannot appear on a single line, the display on the 4th line only will shift
by a single character position to the left each time the user touches a key. (Each
character that goes out of the display area by the left-shift operation is retained in
the memory.)
