ICS3U1 Unit 2 Activity 2: Question 2

// Date: July 19, 2017
// Purpose: To convert any number from 10 - 99 to its word representation

// This line makes the button, btnConvert wait for a mouse click
// When the button is clicked, the convertNumber function is called
btnConvert.addEventListener(MouseEvent.CLICK, convertNumber);

// These lines make the textinputs wait for a mouse click
// When any of these components are clicked, the clearLabels function is called
txtinNumber.addEventListener(MouseEvent.CLICK, clearLabels);

// Declare Global Variables
var num:int;         // number from 10 - 99
var tensDigit:int;   // the tens digit
var onesDigit:int;   // the ones digit

// This is the convertNumber function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function convertNumber(e:MouseEvent):void
