You have now finished modifying the Pythagorean Theorem program
so that you can review the stack at several points during the running
of it. The altered program is shown below:

If you wish, you can use the key in W/PRGM mode to verify
that the program in your HP-67 matches the one shown above.
Running the Modified Program
To run the Pythagorean Theorem program, you have only to key in
the values for sides a and b and press 3 . The HP-67 will now review
the stack contents, then square side b, exchange the contents of the
X- and Y-registers, and review the stack contents again. Finally, the
value for the hypotenuse will be calculated, the stack contents will
be reviewed a third time, and the calculated value for the hypotenuse
will appear in the X-register when the program stops running.
For example, to compute the hypotenuse of a right triangle with
sides a and b of 22 meters and 9 meters:
