Hello!

I am a newbie to the concept of programming for DPMI.  I am doing a DOS
program where I need more than the 640 KB of ram I have access to.

I am compiling my program using the DJGPP compiler.  Do I have to go through
any other hoops to be able to use more than the 640 KB of ram?  Or will
DJGPP just somehow provide access to the rest of the memory?

In other words, Is there any special code I have to write in order to use
the extra memory at runtime?  Or will DJGPP take care of this for me at
compile time?

Sorry if this is a primitive question.  I've never had to do this sort of
thing until now.

Thanks!

John
