Problems; Clearing A Program - HP -34C Owner's Handbook Manual

Simple Programming 49
In this case, a program consisting of 10 keystrokes takes only five lines
of program memory.
Problems
1. What would be the keycodes for the following operations:
(n) (A, (8)(emo), [F](=rms], 17 (Answers: 25 2;
15 13; 14 6; 23, 51, 1).
2. How manylines of program memory would be required to load the
following sections of programs?

Clearing a Program
The Continuous Memory feature of your calculator preserves any pro-
grams loaded into program memory even while the calculatoris turned
off. To clear program memory, turn the calculator on, slide the PRGM-
RUN switch to erem [l , and press (1) CLEAR All lines of
program memory formerly occupied by programs you cleared using (1]
CLEAR are again available for storing new program instructions.
If the programs you cleared occupied more than 70 lines of program
memory, the lines the programs used in excess of the first 70 are auto-
matically reallocated to data storage registers. Note that if you press (]
CLEAR [prem]in RUN mode, the calculator resets to line 000, but
program memory is not cleared.
If power to the calculator is interrupted (that is, battery failure), all
instructions in program memory and all data in the storage registers may
be lost. When poweris restored and the unit turned on, Pr Error appears
in the display to warn ofthisloss.
Creating Your Own Program
In Meet the HP-34C, at the beginning of this handbook, we created a
program that calculated the surface area of a sphere, given the diameter
of that sphere. Now let's create another program to show you how to use
some of the other features of the HP-34C.
