Sure, there's EMS, and XMS, and various other 
tricks, including the HMA. But a program complaining 
about being "out of memory" is almost always out of 
conventional RAM. 

Yes, programs like QEMM can allow multiple programs 
to have their own conventional RAM. But that max 
limit still exists.

I've done stuff like use QRAM and included utilities 
to get 768k of "conventional" RAM on an XT and on a 
286. And used QEMM with multiple tasks/sessions on 
386 and 486 systems. 

So I do have more than a passing familiarity with 
what happens with DOS based software.
