I have finished my shared disk directories program and it seems to be working
(even with  that !"$"!%$ HELP which  calls DMSLADAD without reason  and made it
necessary to define a dummy DCH with no data in non-shared storage...) What the
program allows  you to do is  place the FSTs of  one or more public  disks in a
shared segment and allow the users to  access the disk using the shared copy of
the FST with  a new module, ACCSHR, which  will call ACCESS if it  can't do the
access (eg disk  has been modified since  the shared segment was  saved). I did
NOT want to call it ACCESS and  NUCXLOAD it to override the default ACCESS com-
mand because I  wanted to make sure  that it did not  get invoked unexpectedly.
Our CATIA  V2 R2 is not  working here, and  of course "it's the  system group's
fault and the fault of VM/SP 4 --  it worked under VM/SP 3" (they changed their
FORTRAN procedures  in the meanwhile but  "this can't be the  cause"). Anyway I
don't like overriding default  commands unless absolutely necessary, especially
when it  allows users to  pretend it's our fault  if their programs  don't work
:-)
 
  If someone  is interested  in testing  it I'd be  glad to  send a  copy. Note
however that  I can make no  warranty as to  the thing working properly  in all
conditions or not, and that there  is little documentation. The installation is
fairly  easy though,  provided you  have a  spare DCSS  of reasonable  size and
located at  a convenient address  -- otherwise you'll  have to wait  until your
users allow you to reboot the system... :-(
