Weakly asking, I see many people say that DJGPP and wattom c are 32-bit DOS compilers in protected mode. There's one thing I don't understand. DOS is 16-bit, so how can it run 32-bit things? I'm confused...
Also, how is its memory addressing implemented under 16-bit DOS...
Can someone help explain it in detail...
Thanks...

Programs compiled with DJGPP are of course 32-bit. Some people say "DOS is 16-bit", but in fact this statement is not precise. It can only be said that "the kernel of DOS is 16-bit", and through various DOS extension specifications (such as DPMI) or extenders (such as DOS4GW, CWSDPMI, etc.), DOS can easily support 32-bit mode.

Oh, then if we install DOS now, without other tools, can't we run programs compiled by DJGPP? Does it need to be expanded to support...

Of course not. DJGPP, like other 32-bit programs, already has its own expansion function.
