® DoveSoft Computing July 2009                               Made with Xara Web Designer 7 Premium This application has been written by DoveSoft Computing. It uses both MXML and actionscript 3.0. MXML is a tag-based declarative markup language that you use to compose Flex applications. ActionScript 3 is an object-oriented programming (OOP) language, which means, in general terms, that the fundamental structural unit of your application is an object. Objects expose specific functionality in the form of properties and methods, which you use to interact with the objects. Actionscript is also used with Adobe Flash. ® DoveSoft Computing April 2011 To use the application, simply enter your appropriate values in the text boxes in the left column and click the Calculate button. Any errors in your input, such as omitting a value, are detected using MXML validators and a warning is displayed. When all input is successfully validated, Actionscript is used to calculate the values displayed in the right column. You can update any values in the left column and click Calculate again to display updated results.
