The
Letter
Keys
Mostof the keys have a letter written next to them, as shown
above.
Whenever
you need to type in a letter—which is used to identify a
variableor a label—the A..Z annunciator appears in the display, indi
cating that the letter keys are
'active*.
(Variables
are
covered
in
chapter 3.)
Backspacing
and
Clearing
One of the first things you need to know is how to
clear:
how to
correct numbers, clear the display, and, in general, start over.
