• Pressing jj| clearI clears the contents of the displayed variable.
Press |r/s| to continue the program.
For Example: See the program for 'Solutions of Simultaneous Equa
tions—Determinant Method,* on page 175 in part 4. Lines S24
through S29 at the endof the S routine display the results for X, Y,
and Z. Note also that each VIEW instruction in this program—as in all
the applications programs—is preceded by a RCL instruction. The
RCL instruction is not necessary, but it is convenient because it brings
the VIEWed variable to the X-register, making it available for manual
calculations. (Pressing I enter I while viewing a VIEW display would
have the same effect.)
Example: INPUTting and VIEWing Variables in a Program. Write
an equation to find the surface area and volume ofa cylinder given its
radius and height. Label the program C (for cylinder), and use the
variables S (surface area), V (volume), R (radius), and H (height). Use
these formulas:
V = irR2H
S = 2ttR2 + 2irRH = 2 (irR2 + irRH).
