Hi.
I don't understand how 32 bit programs loads and runs under DOS? Maybe someone can explain me this process. Why can i debug them with 16 bit Turbo Debuger?
Will fpc support component objects for using only or for creating also?

Well I used to debug 16 bit windows 3.1 programmes written in delphi with
turbo debugger (for dos) under windows 95 (when I hadn't got the source).
So.... why not?

It is not answers i expected. I want to how 32 bit command are converted to 16 bit commands if it is so? And how is organized program adress space?

32 bit programmes can be run under a dos extender.
I can't answer about whether or not 16 bit turbo debugger can debug 32 bit programmes or whether or not you were using 16 bit turbo debugger or whether or not there is a 16 bit turbo debugger, but I did say that I was using a "dos" turbo debugger to debug windows programmes.
I don't think I have the real answer for you, sorry

That has not really anything to do with FPC, but with the Dos extender we use (go32 version 2). We didn't write the Dos extender, so we also don't know the details about how it does that. Maybe you can find more information on the website of the author, <http://www.delorie.com>
