(Internally not exactly the same as in BP, but a (well-written) Pascal procedure shouldn't notice the difference.) So the problem concerns only strings as function results and possibly pointer types to strings. In this case, MHO is to change them to bpString because I know that you'll keep an eye on the library, and change them back to String when this will be supported. For other programs, the programmers must decide for themselves whether to use a fixed size string if they're ready to change it back when possible, or to use String and stand some warnings in the meantime. (Of course, warnings can be turned off globally, but as I said on another occasion, I don't like this idea very much.)

Is this correct, Peter? > > program Chief23; [....] Your program works okay - and, you will be happy to hear, I have found the cause of the bug. It was caused by this statement in the initialization section of SYSTEM.PAS; FMode := L_Binary; I have now removed it. Now, this takes me to another point. I need to remove the statement in SYSTEM.PAS that redefines "String" as "bpString" if "_Borland_Pascal_" is defined. This would of course change the definition of all those functions in the unit that either take "String" as parameters, or that return type "String". The question is, what should I change them to? Since this is a bpCompat unit, I could change all of them to "bpString" (or "ShortString", which is currently defined as "bpString"), or I could just leave them as "String", which might mean warnings, etc., and the compiler defaulting to a 255 character length. What do people think? A new version of bpCompat is imminent, and I need to resolve this issue. Best regards, The Chief -------- Dr. Abimbola A.

Strange -- I can't see this bug! I got the binary distribution of gpc-980511 (*) for DJGPP, and tested the following program. (*) The files are dated 11 May -- though GPC gives 2.8.1 as its version number (under Linux as well). Is this correct, Peter? program Chief23; var t:text; s:string(42); begin rewrite(t,'test.dat'); writeln(t,'OK'); reset(t); readln(t,s); if length(s)=2 then writeln(s) else writeln('Failed: ',length(s),' ',s); close(t) end. It writes "OK", though test.dat clearly contains a #13 before the #10. So, if this bug still shows on your system, it must depend on the presence of DosEmu (but why should it?), the version of DJGPP or the phase of the moon. Can anyone else reproduce it?

New GNU Pascal alpha gpc-980511 works with egcs-19980508
by Peter Gerwinski 17 May '98

17 May '98

Hello, everybody! A new alpha version of the GNU Pascal compiler (GPC) is being uploaded to the usual place, ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/alpha/ . News: This version compiles with gcc-2.8.0, gcc-2.8.1, or egcs-19980508 (2.91.28). Compiling with EGCS requires a definition `-DEGCS' given to `make', like the following: make LANGUAGES=pascal CFLAGS="-g -O6 -DEGCS" install This will be automated in the future. Together with the source, I am uploading binaries for Linux (gcc-2.8.1 and egcs-19980508) and DOS (DJGPP). Enjoy - and send your test reports to the GPC mailing list <gpc(a)hut.fi>, Peter -- Peter Gerwinski, Essen, Germany, http://home.pages.de/~Peter.Gerwinski/ Maintainer GNU Pascal - http://home.pages.de/~GNU-Pascal/ - gpc-980511 PGP: see homepage - 6C 94 45 BE 28 A4 96 - 0E CC E9 12 47 25 82 75 Fight the SPAM and UBE! - http://spam.abuse.net/ - http://maps.vix.com/

Re: Can't build GNU Pascal alpha gpc-980511 Cross Compiler

Do you mean to imply I > need to use a gcc-2.8.1 native compiler to compile the gpc source? No. gcc-2.7.2.1 should work fine. The *source* must be 2.8.x or EGCS.

Winapi
by Southpaw 15 May '98

15 May '98

Thank you for the help on Prefixseg. But now I have come across another problem. The compile cannot find winapi.pas or winapi.ppu in my directories and therefore will not finish compiling my program. Can anyone tell me where I can get this? Sorry if this is too much of a simple question but I am new to GNU Pascal. Antonio Hernandez please reply to: southpaw(a)ecs.fullerton.edu

I don't know. I don't usually use such things as word processors, so I have none installed. But I'll try to get those programs you mentioned. (Or do they run only on Windoze? In this case, would you please run them and send me the converted files, if their license permits?) > BTW: RTF is basically ascii text with zillions of formatting codes.

Perhaps HTML might do the job? There are many such standard formats available like HTML with JPEG or some other graphics format, DVI, Postscript, TeX with EPS, or maybe even PDF, all of which should be available on most decent systems. -- Frank Heckenbach, frank(a)pascal.gnu.de http://fjf.gnu.de/ PGP keys: http://pgp5.ai.mit.edu/pks/lookup?op=index&search=Frank+Heckenbach

Well I don't think RTF is Windows specific, I've seen it used quite a bit on Mac and NeXT machines. (I think NeXTMail may even be standardized on it.) It is one of the more portable markup languages around in that a lot of software does cope with it. If you use TeX/LaTeX, any CPAN site should have an RTF converter to those formats. The following site has a converter for RTF-> HTML: http://www.sunpack.com/RTF/latest/ There are both Linux and DOS binaries along with a lot of other operating systems. In my opinion it's best to convert a markup languages to another markup language but I think there is a library of public domain C code to strip RTF codes (of course I can't remember where it was now. :) Hope some of this helps, -Kevin -- Kevin A.
