"One of the first things I like to do when working a new contract is dive into the code and work my way around to understand it," Emil wrote, "one line of code that looked like a good start was this."

private ISelecteVariableProperties[] Iselecvariablelst 
    = new ISelecteVariableProperties[ 7 ];

"The '7' didn't make a lot of sense, but I figured there had to be a good reason. And then I came across the following."

if (Iselecvariablelst[0]==null)
{
  for (int i=0;i<7;i++)
  {
    Rectangle rect =new Rectangle(216,12,110,60);
    if (i>0)
    {
      rect.X = 4+((i-1) % 3)*106;
      rect.Y = 75+((int)((i-1)/3))*60 ;
      rect.Width = 105;
      rect.Height = 60;
    }

      Iselecvariablelst[i]= (ISelecteVariableProperties)
        (theowner.GetStaticControl_SetUp(
          "SelecteVariableProperties", 
          (IBaseProperties)this,
          rect, 
          GroupWrite, 
          true));
      if (Iselecvariablelst[i]!=null)

          Iselecvariablelst[i].GetControl(),

Emil continued, "at that point I decided that some mysteries are better left unsolved."
