Program Memory Basics
Program Memory stores a sequence of entries in calculator memory for re-use
at a later time. A program line is specific number, function key, or decimal
point. For example the ENTER button is a program line. Program lines that
start with b , r , RCL, STO, or GTO buttons have two entries because the
entry is incomplete without describing what comes after the first button.
When executing a program, all instructions therein are performed—all button
sequences are carried out, just like touching the keys manually—and begin with
the current program line proceeding through all the rest of the program lines.
When in program mode, the display screen holds data from the current
program line. To the left of the display screen is the number of the program line
in the program memory.
The rest of the digits describe a code that tells what instruction is stored within
that program line. A program line set to 000 will show no code, because there
is no instruction specified.
To display a program line: touch b , P/R to set calculator to program mode
instead of run mode, this will display the key code and line number for the
calculator’s current program line.
To check some (or all) instruction stored within the program memory: touch

Determining Program Line Instructions
All keys besides the number 0-9 keys on the calculator are described by 2-digit
key codes that correspond with that specific key’s location on the keyboard.
The first number in the key code is the number of the key row, with the first row
being 1-9, and 0 for the 10
th
key. The number keys 0-9 have key codes that
correspond to their values (the number 3 button’s key code is only ‘3’),
therefore storing the R↓ button to a program as an instruction into program
memory displays a line number and key code of 001 33.
