Depends on the version of DOS, but I believe that the most recent 
versions have either 32MB or 64MB limits...  I do know they are 
limited, just not how much by which version.  DOS 7.0 (Win95) appears 
to be limited to 64MB.

One thing that I have found, though, is that though the DOS may be 
limited to the maximum memory available to the running program, it is 
possible to use more.  I have set up 32MB RAMdisks on several machines, 
which I have primarily used as browser cache - it can make a big 
difference in browsing speed, if the cache files can be stored on the 
RAMdisk, instead of the hard drive.  It also makes editing large 10MB+ 
text files much quicker, if you copy them to the RAMdisk first, then 
start editing.
