The CLEAR Keys
Clearing
a register or the display replaces the number in it with zero. Clearing
program memory replaces the instructions there with
gi
000. There are
several clearing operations on the hp 12c platinum, as shown in the table below:
Key(s) Clears:
O
Display and X-register.
f
CLEAR
²
Statistics registers (R
1
through R

), stack registers, and
display.

Î
Program memory (only when pressed in Program mode).

G
Financial
registers.

H
Data storage registers, financial registers, stack and LAST X
registers, and display.
Note:
In ALG mode, it is a good idea to begin calculations by pressing
OO
. This will ensure that there are no pending arithmetic calculations
that might interfere with the solution of a new problem. The reason this key is
pressed twice is that pressing it the first time clears the display and X-register
only, allowing you to correct an erroneous entry by keying in a correct
number. The second press of
O
will clear any pending operations as well.
Pressing the
}
key is another way to ensure that there are no pending
operations before beginning a new calculation, since the
}
key will
evaluate any pending expressions.
