obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

This is followed by an integer object containing a count of +-- the number of service months for the customer. Finally, a +-- two-dimensional array object with monthly consumption information for +-- the customer is written to the stream. +-- +-- Objects of record types with discriminants without defaults should +-- have their discriminants included in the stream when using 'Output. +-- Likewise, discriminants should be extracted +-- from the stream when using 'Input. Similarly, array bounds are written +-- to and read from the stream when using 'Output and 'Input with array +-- objects. +-- +-- APPLICABILITY CRITERIA: +-- Applicable to all implementations that support external +-- Stream_IO files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with FXACB00; +with Ada.Streams.Stream_IO; +with Report; + +procedure CXACB01 is +begin + + Report.Test ("CXACB01", "Check that the default attributes 'Input and " & + "'Output work properly when used with objects " & + "of record, natural, and array types" ); + + Test_for_Stream_IO_Support: + declare + + Util_File : Ada.Streams.Stream_IO.File_Type; + Util_Stream : Ada.Streams.Stream_IO.Stream_Access; + Utility_Service_Filename : constant String := Report.Legal_File_Name; + + begin + + -- If an implementation does not support Stream_IO in a particular + -- environment, the exception Use_Error or Name_Error will be raised on + -- calls to various Stream_IO operations.
