   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''; 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.
