What about PV-Wave? Is there a way to generate linked lists?
If not this certainly would be an advantage for IDL.

There's a nice description of how to use Handles
(i.e. the closest thing IDL has to pointers) to
create linked lists on page 11-19 of the IDL User's
Guide. There's also a nice treatment of the same topic
in the Programming Techniques chapter of "Learning
IDL" if you happen to have that (if you don't you
might think about obtaining it; it's got some useful
stuff in it) Hope that helps some,

Use the HANDLE_CREATE, HANDLE_VALUE, etc., procedures/functions. These
built-in IDL commands make linked lists fairly trivial. See the docs.

For an example of using handles to deal with tree structured data, see
the example idl_tree.pro in the IDL distribution.

I hope this helps.
