A couple of notes on the subject:

	A) The IBM PL/I Optimizing compiler running under VM/CMS has what
	   they call a "transient" library.  I'm not sure about all the
	   details, but I believe this library can be set up (by the
	   system administrator) to reside in a non-volative section of
	   memory.  I think OS/MVS has the same thing.
	
	B) I understand the new AT&T 7300 micro supports some type of
	   shared libraries.  Again, I'm not sure of all the details,
	   but I have heard that you can't use the debugger with a
	   program using the shared libraries.

Anyone want to clarify?
