AFAIK, yes.  But I haven't used Extra Data Segments since I switched to 
MPE/iX.  Under MPE V if you had a really big data stack DS was the only 
way to exceed 32767 bytes (in COBOL) of data storage.  Under MPE/iX, 
there is no such restriction.  Of course, DS will work under MPE/iX, 
but IIRC it's not recommended (some sort of performance hit using 
the intrinsics - probably CM-NM switching).  But there are mapped 
files (not accessible directly from COBOL) which are basically 
DS in a new guise.

This is all from memory, so I could be wrong. :-)
