  Example
  (var pEvent) // pEvent will be a heapPtr
  = pEvent (Event:new())

An array of four variables defining a rectangle

• A pointer to a variable array of four
  Example
  (var rect[4])
  TextSize(@rect)
  = yMin rect[0]
  = xMin rect[1]
  = yMax rect[2]
  = xMax rect[3]

An array of two variables defining a point

• A pointer to a variable array of four
  Example
  (var point[2])
  = y point[0]
  = x point[1]

Void means that the function does not return a value.
