Ben, 

For Classic-Ada(tm) help, you can e-mail our support address (support@sps.com).

Our BIX account was stopped in 1989/1990 due to lack of customer use.  (Even
when we gave out free one year subscriptions!)  Also, your Classic-Ada (CA) 
manual contains an 800 number for CA support.

We interface CA to non-CA to CA code all the time! Since the CA processor 
accepts both Ada and Classic-Ada, you would simply have the bodies of your
messages reference the necessary Ada routines.  You could also encapsulate 
your graphics packages within CA classes.  This would give you an object 
oriented interface to your graphics packages.

For more specific information (I'm trying to be very general here because
I'm unsure of your dilemma) just ask away...

Classic-Ada is used primarily in the business world.  We have many more
business customers than academic customers.

Ada 9X will not impact Classic-Ada or Classic-Ada users.  When Ada 9X 
emerges, the Classic-Ada processor will output Ada 9X code.  Also, we 
will be at least two steps ahead of Ada 9X by providing persistent objects 
as well as multiple inheritance.  We currently have support for persistent 
objects (objects whose data is automatically saved between application 
executions).  We will have multiple inheritance by the time Ada 9X becomes 
real.
