Runnmg a Program
Programs are executed in automatic RUN mode. So first set
the PRGM-RUN switch to RUN erov [l[M~~. Next press
[0][0]. This operation resets the calculator so that program
execution will begin from step 00 (Pressing [l i
RUN mode accomplishes the same thing.) Then, key in a value
for a diameter and press in RUN mode to run your program.
The operations stored in program memory are executed
sequentially downward from step 00. First step 01 is executed,
then step 02, then step 03, and then step 04, which now contains
a special instruction, [o] [0] -
GTO 00
The &8 (0] [0] instruction in step 04 is not an instruction you
keyed in yourself. It was already there. If you press [
in PRGM mode or if you switch the calculator OFF and ON
again, program memory is filled with (o] [o] instructions.
The three-step program you keyed in replaced three of these
instructions. Program memory was changed as shown in the
following illustration.
