In this chapter, you learned how to work with various forms of loops, including the Do_Loop, Do_Until, While_Wend, For_Next, and For_Each loops. These statements provide you with the capability to process large amounts of data and to execute code statements repeatedly with a minimum amount of program code. You also leaned how to work with the ListBox, ComboBox, PopupMenu, and ProgressBar controls, as well as how to work with a REALbasic function that provides access to a standard Open dialog that can be used when working with files and folders. And, last, you learned different ways to break out of endless loops.
