[Dev-C++] memory allocation

[<or...@vp...>]

Hello!

I would like to ask a question, not really related to "modern" programming.

In Borland C++ 3.11 (DOS version) can I allocate memory dynamically. I mean, do 
I need page flipping and stuff like that, or is memory linear?
What if I run Borland C++ written programs under Windows? Shall my programs get 
the memory. How much can I get (in DOS and Windows).

I need help quickly (today) so I would be very happy if you could answer.
Thank you.
