   My project has been tasked to find a way for a C program to call an
   Ada program, passing parameters back and forth.  The two programs must
   be linked as one executable since the Ada program must hold
   information about the C program between calls.  This information must
   be unique to each user executing the C program and can not be altered
   by the C program in any way.

   The project is working on a Gould PowerNode 9050 with a UTX/32
   operating system utilizing the Aplex Ada compiler (version 2.1).

   Our question is: how have other projects/people solved the problem of
   C to Ada parameter passing?  Any information would be appreciated.
   Since this is likely not of interest to the group as a whole please
   e-mail any responses to the address below or call between 9:00 am and
   6:00 pm (EST).  Thanks, in advance, for your help and information.

   FYI : one method that has been mentioned to our group is to utilize
         shared memory.  Unfortunately, we lack expertise in this area.
         If this is something about which you have knowledge, we would be
         interested in hearing from you.
