*** Program calculations are performed automatically with each press of
when it is pressed after data
is input or after the result is read.
*** directly after a program in P0 is executed by pressing
as in this example, the Prog 0
command is stored by the replay function. Therefore, subsequent executions of the same program can be perfor-
med by simply pressing .

4.2 PROGRAM CHECKING AND EDITING (Correction, Addition, Deletion)
Recalling a stored program can be performed in order to verify its contents. After specifying the desired program
area using or in the WRT mode (
), the program contents will be displayed by pressing the
key. Once the program is displayed, the or key is used to advance the program one step at a time for
verification.
When the program has been improperly stored, editing can also be performed by adding to it or erasing portions. Here
a new program will be created by checking and editing the previous sample program (the surface area and volume of
a regular tetrahedron).
Example: Find the surface area and volume of a regular tetrahedron when the length of one side is given
1) Formulas
For a surface area S, volume V and one side A, S and V for a regular octahedron are defined as:
S =
√
3A

V =
A

2) Programming
As with the previous example, the length of one side is stored in memory A and the program then
constructed.

When the above is formed into a program, it appears as follows:
