[AccessD] Bizarre output from recordset properties

[Arthur Fuller]

I'm playing with a simple proc that opens four recordsets and prints their
properties. One of the output lines is this:

NameMap = ??  ????????  ????@ Purchase Order Details   ???????? ????????ID
  ???????? ????????Purchase Order ID   ????????  ???? ??Products   ????????
????????Id   ???????? ????????Product Name   ???????? ????????Product ID
???????? ????    Product Details   ???????? ????????Quantity   ????????
????????Unit Cost   ???????? ????????Date Received   ????????
????????Posted To Inventory   ???????? ????????Inventory ID

The property in question is called NameMap. I don't know what all the
question marks are about. Examining the string, I can see the names of
other column names.
It would be easy enough to trap for the name NameMap, but it has me
curious. Anyone know what it is and what it represents?
