How to read a text file in the App directory?

[Thomas_Sch]

Use AFiles("name")

Each HP Prime app can have any number of files associated with it. These files are sent with the app. For example, if there is a file named icon.png associated with the app, then this file is used for the app icon in the Application Library.
AFiles returns the list of all these files.
AFiles("name") returns the contents of the file with the given name.
