【算法总结】
  注册码12位，前4位任意。
  5-8位根据以下规则转换成另一个数字：
  0 → 8
  1 → 6
  2 → 4
  3 → 0
  4 → 5
  5 → 2
  6 → 9
  7 → 1
  8 → 3
  9 → 7
  转换后的5-8位分别依次与9-12位比较，均相等则注册成功(例如：123456782913)。注册码保存到C:\WINDOWS\system32

\SuperCopy.ini

  算号器源码（VB Code）：
  Private Sub Command1_Click()
  Randomize
  X1 = Int(Rnd * 90000000) + 10000000
  Text1.Text = X1
  For i = 5 To 8
  temp = Mid(Text1.Text, i, 1)
  Select Case temp
  Case 0
  sn = sn & 8
  Case 1
  sn = sn & 6
  Case 2
  sn = sn & 4
  Case 3
  sn = sn & 0
  Case 4
  sn = sn & 5
  Case 5
  sn = sn & 2
  Case 6
  sn = sn & 9
  Case 7
  sn = sn & 1
  Case 8
  sn = sn & 3
  Case 9
  sn = sn & 7
  End Select
  Next
  Text1.Text = X1 & sn
  End Sub
