This Annex contains descriptions of features of the
language whose functionality is largely redundant with other features
defined by this International Standard. Use of these features is not
recommended in newly written programs.]
Ramification: These features
are still part of the language, and have to be implemented by conforming
implementations. The primary reason for putting these descriptions here
is to get redundant features out of the way of most readers. The designers
of the next version of Ada after Ada 95 will have to assess whether or
not it makes sense to drop these features from the language.
Wording Changes from Ada 83
following features have been removed from the language, rather than declared
to be obsolescent:
- The package Low_Level_IO
- The Epsilon,
Mantissa, Emax, Small, Large, Safe_Emax, Safe_Small, and Safe_Large attributes
of floating point types (see A.5.3).
- The pragma Interface
- The pragmas System_Name,
Storage_Unit, and Memory_Size (see 13.7).
- The pragma Shared
Implementations can continue
to support the above features for upward compatibility.
