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.

Initially, the file is +-- opened with mode Out_File, and data is written to the file. The file +-- is closed, then reopened with mode Append_File. An additional record +-- is written, and again the file is closed. The file is then reopened, +-- again with mode Append_File, and another record is written to the +-- file. +-- The file is closed again, the reopened with mode In_File, and the data +-- in the file is read and checked for proper ordering within the file. +-- +-- An expected common usage of Append_File mode would be in the opening +-- of a file that currently contains data. Likewise, the reopening of +-- files in Append_Mode that have been previously appended to for the +-- addition of more data would be frequently encountered. This test +-- attempts to simulate both situations. (Of course, in an actual user +-- environment, the open/write/close processing would be performed using +-- looping structures, rather than the straight-line processing displayed +-- here.) +-- +-- APPLICABILITY CRITERIA: +-- Applicable to all systems capable of supporting IO operations on +-- external Sequential_IO files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 27 Feb 97 PWB.CTA Allowed for non-support of some IO operations +--! + +with Sequential_IO; +with Report; + +procedure CXA8001 is + + -- Declare data types and objects to be stored in the file. + subtype Name_Type is String (1 .. 10); + type Tickets is range 0 .. 1000; + + type Order_Type is record + Name : Name_Type; + No_of_Tickets : Tickets; + end record; + + package Order_IO is new Sequential_IO (Order_Type); -- Declare Seq_IO + -- package, + Order_File : Order_IO.File_Type; -- and file object. + Order_Filename : constant String := + Report.Legal_File_Name ( Nam => "CXA8001" ); + Incomplete : exception; + +begin + + Report.Test ("CXA8001", "Check that all elements to be transferred to a " & + "sequential file of mode Append_File will be " & + "placed following the last element currently " & + "in the file"); + + Test_for_Sequential_IO_Support: + begin + + -- An implementation that does not support Sequential_IO in a particular + -- environment will raise Use_Error or Name_Error on calls to various + -- Sequential_IO operations.
