one more list question

[John Carnahan]

To all,

I have another question about lists.  Is there any way to tell what the 
index of a member within a list is?  I want to know because at a certain 
point I want to build a mirror to one of my id lists, full of ints, so that 
the each indexed int would correspond to its respective id.

Thanks,
