Experts, I'm writing a program under DOS, and I need to use a fairly large amount of space, maybe over ten megabytes. I only know that in big real mode it can address up to 4 G, but I don't know whether the buffer I allocate can reach several megabytes or even more than ten megabytes. Also, if you could tell me how to implement it specifically, I would be extremely grateful!

Using big real mode is unsafe; it's better to use protected mode under DOS. Besides, there are already many DOS protected-mode program development tools. The one I use most often is Free Pascal.

Right, Free Pascal and DJGPP C/C++ are both quite good.

I found something even better than Free Pascal. With it, you can use Delphi (it even supports Delphi 7!) to develop DOS programs, and it supports Forms too. Incredible, right? But I really have tried it. It's really easy to use.

Delphi for DOS is really something I've never heard of before; I just downloaded it.

The latest version now is 2.2.0, which can be found and downloaded from its website.
Right now I'm working on long filename support for the system functions and classes in this version.

Today I've basically finished correcting system.pas (only one function left). Hopefully tomorrow I can finish correcting windows.pas or sysutils.pas.
