Any 3090 AIX routines to call MVS?

[CRAYJOHN at cc.utah.edu]

I am new to AIX UNIX so please bear with me if this is a simple minded
question.  I do alot of large scale scientific modeling on an IBM 3090/600S
supercomputer at the University of Utah.  Recently, I have had the pleasure
of using a new IBM RISC/6000 workstation running AIX.  The folks at the 
supercomputing institute have now made the 3090 available running AIX, but
it won't process the really large jobs.  My question is, are there any
subroutines out there which one can make calls to MVS from within AIX?
