4/2
5/2
{AI95-00434-01} See also: 3.5.9, “Fixed Point Types”; 3.5.10, “Operations of Fixed Point Types”; 4.6, “Type Conversions”; 13.3, “Operational and Representation Attributes”; A.10.9, “Input-Output for Real Types”;B.4, “Interfacing with COBOL”; B.3, “Interfacing with C and C++”; B.4, “Interfacing with COBOL”; Annex G, “Numerics”.
6
The character and string handling packages in Annex A, “Predefined Language Environment” are also relevant for Information Systems. 

Implementation Advice

7
If COBOL (respectively, C) is widely supported in the target environment, implementations supporting the Information Systems Annex should provide the child package Interfaces.COBOL (respectively, Interfaces.C) specified in Annex B and should support a convention_identifier of COBOL (respectively, C) in the interfacing pragmas (see Annex B), thus allowing Ada programs to interface with programs written in that language. 
7.a/2
Implementation Advice: If COBOL (respectively, C) is supported in the target environment, then interfacing to COBOL (respectively, C) should be supported as specified in Annex B.

Extensions to Ada 83

7.b
{extensions to Ada 83} This Annex is new to Ada 95. 

Wording Changes from Ada 95

7.c/2
{AI95-00285-01} Added a mention of Wide_Wide_Text_IO.Editing, part of the support for 32-bit characters.
