Yellow: Operation Keys The yellow keys are used for writing and correcting programs. Detailed explana-
tions of their functions are given later in this section.
Except for the SHIFT key on the upper right, the gray keys are used to input
instructions and designate data area prefixes when inputting or changing a pro-
gram. The SHIFT key is similar to the shift key of a typewriter, and is used to alter
the function of the next key pressed. (It is not necessary to hold the SHIFT key
down; just press it once and then press the key to be used with it.)
