Using Equations to Display Messages
Equations aren't checked for valid syntax until they're evaluated. This means you
can enter almost
any
sequence of characters into a program as an equation — you
enter it just as you enter
any
equation. On any program line, press
to start
the equation. Press number and math keys to get numbers and symbols. Press
before each letter. Press
to end the equation.
If flag 10 is set, equations are
displayed
instead of being
evaluated
. This means
you can display any message you enter as an equation. (Flags are discussed in
detail in chapter 14.)
When the message is displayed, the program stops — press
to resume
execution. If the displayed message is longer than 14 characters, the
annunciator turns on when the message is displayed. You can then use
Õ
and
Ö
to scroll the display.
If you don't want the program to stop, see "Displaying Information without
Stopping" below.
Example:
INPUT, VIEW, and Messages in a Program.
Write an equation to find the surface area and volume of a cylinder given its radius
and height. Label the program
C

cylinder),
and use the variables
S
(surface

V
(volume),
R
(radius), and
H
(height). Use these formulas:
