 AFAIK, the name EMMXXXX0 is part of the EMS 
standard, meaning any EMS manager MUST use 
use this device name. 

 I am not a programmer, just a long-time DOS 
user, but never saw an EMS manager otherwise 
named. Would you please provide an example? 

 Also, there are some fastidious recommended 
tests for detecting an EMS manager, both in 
official (MS DOS Encyclopedia) and unofficial 
(Ray Duncan's "Extending DOS") literature. 
Either use, as a first step, the detection of
a file or device named EMMXXXX0 in the current
working directory and does not proceed if none
is found.
