Annex F


Information Systems

This Annex provides a set of facilities relevant to Information Systems programming. These fall into several categories: 
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.3, “Interfacing with C and C++”; B.4, “Interfacing with COBOL”; Annex G, “Numerics”.
The character and string handling packages in Annex A, “Predefined Language Environment” are also relevant for Information Systems. 

Implementation Advice

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.
