Programming the RPN-32

A program is nothing more than a sequence of manual keystrokes that is remembered by the calculator. You can then execute the program as often as you like – typically with just one keystroke. The answer displayed at the end of execution is the same one you would have obtained by pressing the keys one at a time manually. No prior programming experience is necessary for RPN-32 calculator programming.

To get you started, try entering and executing the sample program shown on the Info screen of RPN-32 CE (double-tap the calculator name at the bottom).

Entering and running a program

Reviewing your program

Debugging your program

Editing your program

Adding or removing steps will automatically adjust all affected GTO commands.
For example, if you enter GTO 40 after step 10 to branch to line 40, what gets stored is GTO 41, since your instruction caused the rest of program memory to move down one line.
However, if the GTO's target lies in the unused program area past your last program step, no adjusting takes place.

Indirect Addressing (STi, RCi)

Note that the indirection register R.9 may be incremented, decremented and tested by the loop control instructions DSE and ISG.

Example program 1 – Sum of 1 to x

Example: Find the sum of all integers from 1 to 100.

Solution: Enter 100, tap R/S. Result: 5050

(Caution: Large values of x will cause RPN-32 CE to become unresponsive.)

Example program 2 – Quadratic Equation

Find solutions to the three equations below:

1.  x² + x - 6 = 0
2.  2.25x² + 3x + 1 = 0
3.  2x² - 3x + 5 = 0

6 CHS ENTER 1 ENTER R/S → 6.2500 (D > 0, so solutions are real)
After 2 seconds:
→ -3.0000 (x₁)
→ 2.0000 (x₂)

1 ENTER 3 ENTER 2.25 R/S → 0.0000 (D = 0, so solutions are real and equal)
After 2 seconds:
→ -0.6667 (x₁)
→ 0.6667 (x₂)

5 ENTER 3 CHS ENTER 2 R/S → -1.9375 (D < 0, so solutions are complex)
After 2 seconds:
→ 0.7500 (u)
→ 1.3919 (v)
x₁,x₂ = 0.7500 ± 1.3919 i
      Managing programs on RPN-32 CE
      Use P/R to select program mode.
Tap the display to open the program listing.
Note that the current step is highlighted:
      Steps may be deleted by swiping left across the line:
      Tap Load to copy the changed program to the calculator.
To exit without changing the program, tap Cancel.

If you select a line before exiting, the line will be shown on the calculator display.

      Exporting a program
A program may be saved for later use or archiving purposes.

Importing a program
To import a program from the Documents folder:

An empty program saved with registers will only replace the registers, leaving the program memory untouched.
This feature may be used to create pure data files.
Deleting the current program
