Yes it does.  But the article to which I was replying hard said "OS", not
"DOS".

Its always been my understanding that the Atari DOS _started out_ as a 
port of CP/M 68K.  But at least according to various comments I've read
from DRI folks, Atari made various changes in CP/M 68K in order to make it
much more like MS-DOS.  I never grasped why; maybe an effort to ease ports
from the PC world (aren't the BIOS calls even numbered the same under TOS
and MS-DOS?).  That's why CP/M 68K doesn't reportedly suffer from a number
of bugs that exist in TOS.

Well, that's how I heard it (not claiming any special accuracy...)
