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.

A procedure +-- is defined that will take as parameters a source string along with +-- a substring that is to be completely removed from the source string. +-- The source string is parsed using the Index function, and any substring +-- slices are replaced in the source string by a series of X's (based on +-- the length of the substring.) +-- Three lines of text are provided to this procedure, and the resulting +-- substitutions are compared with expected results to validate the +-- string processing. +-- A global accumulator is updated with the number of occurrences of the +-- substring in the source string. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with Ada.Strings; +with Ada.Strings.Fixed; +with Ada.Strings.Maps; +with Report; + +procedure CXA4002 is + +begin + + Report.Test ("CXA4002", "Check that the subprograms defined in package " & + "Ada.Strings.Fixed are available, and that " & + "they produce correct results"); + + Test_Block: + declare + + TC_Total : Natural := 0; + Number_Of_Lines : constant := 3; + + type Restricted_Words_Array_Type is array (1..10) of String (1..10); + + Restricted_Words : Restricted_Words_Array_Type := + (" platoon", " marines ", " Marines ", + "north ", "south ", " east", + " beach ", " airport", "airfield ", + " road "); + + subtype Line_Of_Text_Type is String(1..25); + type Page_Of_Text_Type is array (1..Number_Of_Lines) + of Line_Of_Text_Type; + + Text_Page : Page_Of_Text_Type := ("The platoon of Marines ", + "moved south on the south ", + "road to the airfield.
