Curly braces

ActionScript event handlers, class definitions, and functions are grouped together into blocks with curly braces ({}). You can put the opening brace on the same line as your declaration or on the next line, as shown in the following examples. To make your code easier to read, it's a good idea to choose one format and use it consistently.

// Event handler
on(release) {
  myDate = new Date();
  currentMonth = myDate.getMonth();
}

on(release) 
{
  myDate = new Date();
  currentMonth = myDate.getMonth();
}

// Class
class Circle(radius) {
}

class Square(side)
{
}

// Function 
circleArea = function(radius) {
  return radius * radius * MATH.PI;
}
squareArea = function(side) 
{
  return side * side;
}
