{00434AI95−00434−01} See also: 3.5.9, "3.5.9 Fixed Point Types"; 3.5.10, "3.5.10 Operations of Fixed Point Types"; 4.6, "4.6 Type Conversions"; 13.3, "13.3 Operational and Representation Attributes"; A.10.9, "A.10.9 Input-Output for Real Types"; B.3, "B.3 Interfacing with C and C++"; B.4, "B.4 Interfacing with COBOL"; Annex G, "Annex G Numerics".
6
The character and string handling packages in Annex A, "Annex A Predefined Language Environment" are also relevant for Information Systems.
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.
7.b
{extensions to Ada 83} This Annex is new to Ada 95.
7.c/2
{00285AI95−00285−01} Added a mention of Wide_Wide_Text_IO.Editing, part of the support for 32−bit characters.
