- DISPLAY CLEARING             
DISPLAY CLEARING
The calculator has two types of display clearing operations: CLx(clear X) and <-(back arrow).

In Run mode:
	• CLx clears the display to zero.
	• <- deletes only the last digit in the display **if digit entry has not been terminated** by ENTER or most other functions. You can then key in a new digit or digits to replace the one(s) deleted. If digit entry **has** been terminated(I'll be back), then <- acts like CLx.

In Program mode:
	• CLx is programmable: it is **stored** as a programmed instruction, and will not delete the currently displayed instruction.
	• <- is **not** programmable, so it can be used for program correction. Pressing <- will delete the entire instruction currently displayed.
