Autoplay Menu Designer provides several ways to program complex behavior of your application. One of the available tools here is variables. Variables are named “containers” for certain values – numeric, textual and others. The term “variable” reflects the major feature of such containers – the value they store can change or be changed.

Variables let you control the flow of execution of your application, provide different reaction of the application to user’s actions, check if given conditions are met, modify properties of objects of your application and many more.

The value of a variable can hold numbers, strings or Boolean values. But it also can hold an expression. Expressions are combinations of constants, variables, mathematical, string or Boolean operators, parentheses and functions. Each expression evaluates to some result.
