-- intends to confer upon all recipients unlimited rights equal to those

--
-- Notice
--
-- The ACAA has created and maintains the Ada Conformity Assessment Test
-- Suite for the purpose of conformity assessments conducted in accordance
-- with the International Standard ISO/IEC 18009 - Ada: Conformity
-- assessment of a language processor. This test suite should not be used
-- to make claims of conformance unless used in accordance with
-- ISO/IEC 18009 and any applicable ACAA procedures.
--*
-- OBJECTIVE:
-- Check, for enumeration output, that output that
-- does not fit on the current line is handled correctly.
--
-- TEST DESCRIPTION:
-- RM A.10.6(8), A.10.10(10,11); AI05-0036-1
--
-- An enumeration type with one literal is defined and Ada.Text_IO.Enumer-
-- ation_IO is instantiated with it.
-- An Out_File is created with a bounded line length.
-- The literal is output to the file with a Width parameter so that it does
-- not fit on the current line so that a new line must be inserted first.
-- Then it is output to the file with a Width parameter that it does not fit
-- on the bounded line so that Layout_Error must be propagated.
--
-- The file is reset to In_File and the contents compared to the expected one
-- (b stand for the blank character):
-- 12345678901234567890 <- Col number
-- bbbbbbbbbb
-- LITERALbbbb
--
-- The test passes if it raises Layout_Error at the second Put and if the
-- resulting file has the contents shown above.
--
-- Author: Christoph Karl Walter Grein
--
-- CHANGE HISTORY
-- 16 Jan 07 CKWG Created test.
-- 30 May 13 RLB Minor changes for issuing (added AI number to description,
-- improved wording of objective, simplified wording of
-- messages).
-- 23 Jan 14 RLB Added missing Not_Applicable checks.
