User's Guide - Key Concepts
AutoPlay Media Studio includes special actions that you can use to build control structures like "IF blocks" and "WHILE loops" into your action lists. These control structures allow you to set conditions that will affect the sequence or "flow" of your action lists at run time.
For example, you can use IF and END IF actions to create conditional blocks. A conditional block is simply a group of actions that will only be performed when the condition that you enter in the preceding IF action is met at run time. In plain English, a conditional block would be expressed as: "if the condition in the IF action is true, then do this; otherwise, do something else."
Control structures allow your AutoPlay application to react to different situations in different ways. Does the user already have the evaluation version of your software installed? Is an Internet connection available? You can use actions to answer these kinds of questions and have your application respond accordingly.
