c++.dos.32-bits - Newbie needs help

Hello, I have the digital mars CD.  
I have about 8 programs written 
using DJGPP (before my hd crashed!) and 
now want to run these programs in DM.
The programs were written in plain 'C'.

Im running Windows ME at present, and want
to compile and ammend these programs.  What
target do I need to use, so that I can use
the debugger to step through the code etc.

Also the programs dynamically allocate large 
amounts of memory, should this cause a problem
with some targets?

Kind regards

Use the x (-mx switch) memory model. You'll also need to download the
dosextender from www.dosextender.com. Unfortunately, there isn't a debugger
for it. I recommend debugging it first as a win32 console program, and then
porting it to dos32.

Or, why not just make them win32 programs?

To make them Win32 programs, do I just need to build/compile
them with a Win32 as the target?

Also I used commands like    gotoxy(10,20); where do I find 
alternatives for this?

Thanks for your help

Yes and you need to convert all "legacy dos api calls" to win32 
equivalent api calls. Or write some adaptor layer for it.

Information is in de MSDN (also online). Search for "Console" 
applications or Charater-mode applications.

Yes, as long as you convert any DOS specific calls to win32 calls.


 Also I used commands like    gotoxy(10,20); where do I find
