Selecting distribution table results and selecting [Sample Data] on the [Display] menu will change them to sample data in list form.

2-12 Running a Program in the Main ApplicationYou 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)”.
