CopyMemory Resultl, B(0), 4

CopyMemory Resultl, B(0), 4
哪位大侠知道这具体是什么意思
 A(0) = "&H" + CStr(Hex(recive(6)))
  A(1) = "&H" + CStr(Hex(recive(5)))
  A(2) = "&H" + CStr(Hex(recive(4)))
  A(3) = "&H" + CStr(Hex(recive(3)))
   
  For p = 0 To 3
  B(p) = A(3 - p)
  Next p
  CopyMemory Resultl, B(0), 4
  dd = Resultl
请问dd的值是多少呢，大家帮忙看看啊
