Hello, My name is Scott A. Moore, I am the person who performed some of the ISO 7185 compliance testing on GPC. I have done a minor update to some of my ISO 7185 compliance testing material, and reran this against the current version of GPC (2.95). In the process, I have discovered a compliance problem with GPC. Please reference the program: ============================================================== program test(output); var f: text; c: char; begin rewrite(f); writeln(f, 'how now'); writeln(f, 'brown cow'); reset(f); write(''''); while not eof(f) do begin if eoln(f) then write('<eoln>'); read(f, c); write(c) end; write(''''); writeln(' s/b ''how now<eoln> brown cow<eoln> '''); rewrite(f); writeln(f, 'too much'); write(f, 'too soon'); reset(f); write(''''); while not eof(f) do begin if eoln(f) then write('<eoln>'); read(f, c); write(c) end; write(''''); writeln(' s/b ''too much<eoln> too soon<eoln> '''); end. ================================================================ The results from GPC for running this command are as follows: ================================================================ C:\TEST>test 'how now<eoln> brown cow<eoln> ' s/b 'how now<eoln> brown cow<eoln> ' 'too much<eoln> too soon' s/b 'too much<eoln> too soon<eoln> ' C:\TEST> ================================================================ The first section of the test verifies that eoln in text file is replaced with space, GPC passes this. The second section of the test verifies that eoln is automatically inserted at the end of a text file if it was terminated without a eoln. See ISO 7185 section 6.4.3.5: ===================================================================== There shall be a file-type that is denoted by the required structured-type-identifier text. The structure of the type denoted by text shall de ne an additional sequence-type whose values shall be designated lines. A line shall be a sequence cs ~S(end-of-line), where cs is a sequence of components possessing the char-type, and end-of-line shall represent a special component-value. Any assertion in clause 6 that the end-of-line value is attributed to a variable other than a component of a sequence shall be construed as an assertion that the variable has attributed to it the char-type value space. If l is a line, then no component of l other than l.last shall be an end-of-line. There shall be an implementation-defined subset of the set of char-type values, designated characters prohibited from text les; the effect of causing a character in that subset to be attributed to a component of either t.L or t.R for any text le t shall be implementation-dependent. A line-sequence, ls, shall be either the empty sequence or the sequence l ~ ls' where l is a line and ls' is a line-sequence. Every value t of the type denoted by text shall satisfy the following two rules: a) If t.M = Inspection, then t.L ~t.R shall be a line-sequence. b) If t.M = Generation, then t.L ~t.R shall be ls ~cs, where ls is a line-sequence and cs is a sequence of components possessing the char-type. ==================================================================== Basically, the rules say that a text file shall consist of either whole lines, or be entirely empty. Whole lines are defined as "~S(end of line)", or a series of arbitrary characters terminated by end of line. In effect, the program processor must arrange for eoln to be true at the end of a file, either by faking it while reading, or by forcing an eoln to be written at the end of a file during generation. Thank you for your attention.
