Hi there,

I just recently started out with DJGPP because of the out-of date
technology in the last good DOS-based C compiler BC 3.1

Anyways, after receiveing over 700 mails on my first subscription to
this list, I decided to forgo reading them all (I understand there are
over 150 new ones every day?) and just will post a few questions that
arose during my work with it in the last 4 weeks. If there's a thread
to that, feel free to point it out to me.

My first one would be: how is the portability between DJGPP written
under DOS and Linux?
Basicly speaking it should be fine, but if anyone has experience with
it, I would appreciate any comments.

Second one: I know DJGPP has access to the full Memory in my system
(Pmode and that stuff), so we're talking about no more Memory model
worrys right? If I felt like it I could construct a two dimensional
array with over 64kb of Space? (e.g. char string[32000][32000]) (old
BC 3.1 user :-)) I could also just make my heap a few million bytes
big and use that as buffer? (not the best idea, I know we're talking
theory here)

Third: I experimented with Allegro and I found out that when I
initialize Keyboard, Timer or something like that and want a
return_message (int), the software will not initiallize correctly. As
soon as I took out the return int, it went fine. Is that a prob with
Allegro? In the short doc it states that one generally isn't
interrested in the return code, but I would just like to know if
everything went well. It might have been that the author thought that
nobody would use it anyways so he might have not taken care of his
return code (in-line assembler or so???)

Forth: One thing I realized with RHIDE. It tends to let the mouse
pointer vanisch if you switch to a graphical User Screen and the
switch back. Is that a known prob or n purpose??

Thanx for any good replies....

                    Eddie
