5 Statements - Ada 95 Rationale
There is naturally very little change in this classical area of the language. The only additional statement is the requeue statement and that is addressed in Chapter 9. There are also additional forms of the delay and select statements and these are also discussed in Chapter 9. The mechanism of assignment including user-defined assignment is closely associated with controlled types and these are discussed in 7.4. The return statement is now moved to Chapter 6 where it properly belongs.
