(Just as with regular ZBasic procedures, the compiler automatically inserts the specified default value if you omit one or more of the right-most parameters on a particular invocation.) If that were done, the constructor would have the form shown below. Public Sub _Create(ByVal h as Byte = 0, ByVal m as Byte = 0, _ ByVal s as Single = 0.0) Call SetTime(h, m, s) End Sub When you define an array of objects, you may specify different constructors for each element of the array as shown in the example below. In this particular case, explicit constructor invocations were specified only for three of the ten elements of the array of objects. The remaining elements are initialized using the default constructor – one that can be invoked with no parameters. You may also specify a constructor list for multi-dimension arrays. In that case, the constructors are applied sequentially to the elements of the array with the leftmost index varying the fastest. This corresponds with the way that arrays are laid out in memory. Dim t2(1 to 10) as MyTime = { _Create(12), _Create(), _Create(1, 2) }
