I wanted the same information a while ago and was unable to find it
in any of the documentation or MACRO libraries.  I never pursued it
any further at the time, but with the success I found concerning
LIB$FIND_IMAGE_SYMBOL, I decided to see if I could find the answer
to your question on the microfiche.  The fiche that I was looking at
were for VMS 4.6, the card was 0284, and the frame was J-2.  There is
a definition there that looks like it might be what you're looking for.
If you have fiche for a different version of VMS, the file is MAILDEF.SDL.

P.S. The card which contains the index for the whole set is always the
     last card in the box.
