Yes. but Dev-C++ needs an object oriented approach (C doesn't do this), so
there is two possibilities for me Delphi or C++. I currently prefer to write
it in Delphi since it will speed up development time. Anyway, there is still
a few months of reflexion before this port will be started.

Colin

Hmm... i don't have a clue about this license yet, the only thing i know is
that the compiler will be free.

Check to make sure that you have system("PAUSED"); just before return 0. It
should be there as part of the template for new source code though.

You have not allocated any memory space and assign it to the  pointers.

The function itoa is available in C, but I could not readily find a
reference.  Maybe it's not ANSI standard.  You use it like this:

                                        itoa (some_int, c_array, Decimal);

where
                some_int is an integer,
                c_array is a character array, and
                Decimal is a format indicator.

Of course, you can make up your own function to do this, too.

All of a sudden, I started getting an "illegal operation" in a while loop.
I cut everything out of the loop, but I still get the error.  The pertinent

            If I change "input_file.getline(buffer, 200, '\t')" to

From what I saw of what you plan to do I would recommend using STL vectors.
They are almost exactly like arrays except they can grow as needed to hold
as much as your ram will allow. To find out more about vectors (And the rest
of the standard C++ template library) check out these websites..

Thank you.

It seems to me that it would make sense to write a cross platform 
tool in a language that was supported by most POSIX compliant 
systems. ^^;;

That's just my oppinion.

The compiler will be free to be downloaded, but can one make and sell (or do
whatever) with that free-for-download compiler? Borland has its Win32 C++
compiler free for download but it has a large license agreement which leaves
me the impression that you can not make commercial programs with it and sell
them (or have them free for download, it is the same thing).

I guess bSD won't be supported, since Dev-C++ will be rewrote in Kylix
(Delphi for Linux). If Qt is portable to BSD then it maybe we will a chance

There are several problems with your code, firstly the syntax of line

Hello !

Yes, some bugs may occurs on version 4.0 and 4.01. As you may know Dev-C++
(and Dev-Pascal) will be rewrote in a couple months, and the IDE will now
work with tab sheets instead of MDI windows for editing source files (the
MDI thing under Windows is quite buggy and not powerful at all). The IDE
will also be ported to Linux, as it is a really more stable system than
Windows, and a very powerful platform to develop on.
But this will need a lot of work to have a stable release of this new
version, so don't expect to see something usable until 3-6 months :-(

Greetings,
Colin
