D'oh!!
This cracks me up! I nominate myself for the
prestigious 'Stupidest Question of the Year".
If I may summarize the previous posts:
Q: How do I SAVE my LINKEDLIST in a FILE called 'MYLINKEDLIST.SAV'?
A: SAVE , LINKEDLIST , FILE = 'MYLINKEDLIST.SAV'?
I think this may be the most self-answered question posted
in a long long time.
I was fooled by impressive ignorance.
I tried to look at the linked list object
(in a method called "save_database" and
self appeared to be just a structure
with 3 elements (head, tail, count).
It even had a size of
IDL> print,size(self)
0 11 1
so I was pretty sure saving that wouldn't work.
But it does, how strange and wonderful!
(I had the impression that it would be
saving "pointers to arbitrary positions")

My statement was said a bit prematurely.
As I stumble through (mostly bad) ideas on how best to
do "this", it really has been crawling along
(i.e. it would take a few seconds to get a
screen of text up, but the delays seem to be
in creating and manipulating objects. Saving
them all, and reading and keeping it all in memory
will solve that problem)
Thanks for the info!
cheers,
bob
PS David, when is the "object oriented programming in IDL" book
going to be finished?
