Example

Sub UserProc;
Var
    ArrayL: IArrayList;
    i: Integer;
Begin
    ArrayL := New ArrayList.Create;
    For i := 0 To Math.RandBetweenI(0, 100) Do
        ArrayL.Add(Math.RandBetweenI(0, 100));
    End For;
    If ArrayL.Contains(50) Then
        Debug.WriteLine("The array contains the value 50");
    Else
        Debug.WriteLine("the array does not contain the value 50");
    End If;
End Sub UserProc;

After executing the example a dynamic array with random values is created. The development environment console displays information about presence of the 50 value in the array.
