This don't work with djgpp because it use PROTECTED MODE memory
managment, so you can't directly read/write to system areas that
are out of you own memory area.
There are functions to read/write dos-memory (dosmemput, 
dosmemget) which will do the job for you.

Better than that, Robert Hoene have a port of Borland's Turbo Vision
library for djgpp. With that you'll can do nice windows/menus... in
text-mode. look to his home page :

Yes, you can. Compile your asm source with TASM using *FLAT* model and
then use the obj2coff converter.


The URL for this converter as well as all answers to your (these) questions
are IN THE FAQ !!!!

So get it and READ THE FAQ.
