We are in the process of evaluating several Ada systems for an
upcomming project.  This project involves software development on DEC
and Sun workstations.  It consists of realtime and non-realtime Ada
software components distributed across DEC, Sun and 680X0 target platforms.

Comments based on experience with Ada systems ( Alsys, Telesoft, Verdix... )
would be greatly appreciated.  Below is a brief list of topics we are
concerned with.

  o Foreign language interface ( i.e., C, Fortran, etc.)
    - Effect on task scheduling ( time slicing )

  o Communication between separate computer systems
    - Serial ( TCP/IP, RS232... )
    - Bus ( Q-bus, VME... )
    - DIADEM ( DIstributed Ada DEMonstrated  ) or other programming
      environments for distributed systems.  ( Does anyone have an 
      environment based on the DIADEM work? )
                     ___________________________
  o Speed           |                           |
    - Development ( `->edit->compile->link->run-' )
    - Compilation
    - Code execution including Context ( task ) switching

  o Documentation Quality and Customer Support

  o Bugs, deficiencies

We would also like to locate Ada bindings ( preferably public domain or free )
for several software packages:

  o X-Windows

  o PHIGS ( Programmers Hierarchical Interactive Graphics System )

  o Sybase

  o GRASS ( Geographical Resources Analysis Support System )

  o GALAXY ( or any environment for programming distributed systems ).

I would be glad to forward our findings to anyone who is interested.
