Running a Program in the Main Application

You can run a program in the Main application or the eActivity application.

Syntax:

Folder name\Program name(parameter)

• You do not need to specify the folder name if the program you want to run is in the current folder. If you leave

ClassPad configured with its initial default settings, the current folder for both the Program application and the
Main application is the “main” folder, so you normally do not need to specify a folder name.

• Unless you change it, the current folder of the eActivity application is the “eAct” folder, so you always need

to specify the folder name. If you want to run a program that is in the “main” folder, input “main\Program
name(parameter)”.

Important!

If the program command “Pause” is used in a program, it is ignored when the program is called from Main or
eActivity.

Program

Main application

eActivity application

0248

To run the program named OCTA that we created and stored under “Creating a Program” (page 197) from

the Main application, and determine the surface area and volume of a regular octahedron with a side

length of 20 cm
