Actual program contents are identical to manual calculations. The following shows
how the calculation of the surface area and volume of a regular octahedron would
be calculated using a manual calculation.
Surface Area S ..
c* !9 d*
<value of A>
xw
Volume V ...........
!9 c/d*
<value of A>
M d w
You could also perform this calculation by assigning the value for the length of one
side to variable A.
Length of One Side A
............ <value of A>
a a A w
Surface Area S ..
c* !9 d* a A xw
Volume V ...........
!9 c/d* a A M d w
If you simply input the manual calculations shown above however, the calculator
would execute them from beginning to end, without stopping. The following
commands make it possible to interrupt a calculation for input of values and
display of intermediate results.
? : This command pauses program execution and displays a question mark as a
prompt for input of a value to assign to a variable. The syntax for this com-
mand is: ?
→
<variable name>.
^ ^ ^ ^ ^
:
This command pauses program execution and displays the last calculation
result obtained or text. It is similar to pressing
w
in a manual calculation.
