in thread What's in a Reference?

Different question than last night. He's asking for the relation between the following and $y. 
SV = RV(0x63fde0) at 0x604fc0
  REFCNT = 1
  FLAGS = (PADBUSY,PADMY,ROK)
  RV = 0x604fa0
  SV = IV(0x62de60) at 0x604fa0
    REFCNT = 2
    FLAGS = (PADBUSY,PADMY,IOK,pIOK)
    IV = 42                         <---

    Well, I don't know what was being discussed last night, but I understand the question kind of like this:

    "A C reference/pointer holds an address, what would you call the analogous thing which a Perl reference holds?"  As the subject says: "What's in a reference?"

    Anyhow, only Xiong call tell what he really meant.

      Ah right, I thought he asked 

      $3 = 3;
$2 = \$3;
3 is the ________ of $2

      instead of 

      $3 = 42;
$2 = \$3;
3 is the ________ of $2

      There's not even a 3 in his setup.

        Since he starts of with addresses 1 2 3, then said the sigil '$' means 'address', I just assumed he meant $3
