    I am trying to port programs runing on VM/CMS
to run on AIX/370 (IBM 3090). These programs use
binary files to exchange data. Therefore
direct access method must be used. 

    On CMS the Fortran utility subroutines like
RWFIL, UOPEN, UCLOSE, RDPOS, etc. are used. However,
my consultant says that these utilities are 
obsolete and suggest me to write subroutines
to mimic the Fortran utility subroutines or
use standard Fortran 77 open/close calls. 
These suggestions are both too hard for me. 

    Before I give up, I wonder if the net has
something to offer. I am familiar with Fortran and
C only at the rather novice level, but I am willing
to spend the time.

    Thanks in advance!!!

Sincerely,
Mingzuo Shen
