Programming in HP PPL 523

1. In the Application

Librray, select the

Statistics 1Var app

but don’t open it.

I Select

Statistics

1Var.

2. Tap

3. Enter a name for the new app (such as

DiceSimulation.)

4. Tap twice.

The new app appears in the Application Library.

5. Open the Program Catalog.

6. Tap the program to

open it.

Each customised

app has one

program associated

with it. Initially, this

program is empty.

You customize the

app by entering functions into that program.

At this point you decide how you want the user to interact

with the app. In this example, we will want the user to be

able to:

• start and initialize the app, and display a short note

• specify the number of sides (that is, faces) on each

die

• specify the number of times to roll the dice

• graphically display the results of the simulation

• numerically display the results of the simulation.

With that in mind, we will create the following views:

START, ROLL DICE, SET SIDES, and SET ROLLS.

The START option will initialize the app and display a note

that gives the user instructions. The user will also interact

with the app through the Numeric view and the Plot view.
