I'll check that book out.

New question.

In Ada SPARK how do I make use of an object composed of multiple protected types?

   type Composed is record
      A : A_Type;
      B : B_Type;
   end record;

if Composed is not Volatile the code does not compile. If Composed is Volatile I cannot pass A and B into subprocedures.
