My name is Sam Carter.  I work for a company called ENSCO, Inc in
Springfield, Va.  We have recently been tasked to port a rather large
system written in FORTRAN on a VAX running VMS to a Sun/Unix 
environment.  One of the conditions of this port is to write software
to emulate many of the SYS$ and LIB$ system routines which are currently
used in the software.  The main idea is to keep the interface and 
functionality of the calls the same and just convert the underlying
code to be Sun/Unix compatible.  Our chief problems are in dealing with
asynchronous QIO requests and getting job/process information, but we
are also using several (~45) other SYS$ routines and about 20 LIB$ routines

So the questions are:
	1) Has anyone done something like this before that
	   you would be willing to share either information
	   or code.

	2) Has anyone dealt with asychronous I/O before and
	   do you have any tips.

	3) Is there any other info that you would care to supply.

Any info will be muchly appreciated and can be emailed to:

	via	seismo.CSS.GOV and the Center for Seismic Studies.

Thanks to all.
