SINCE MAKING THE INITIAL SUBMISSION TO THE SPRING DECUS TAPE,
RSX-11M-PLUS-V2.1 ARRIVED.  THERE ARE SEVERAL CHANGES TO THE
EXECUTIVE DIRECTIVE COMMONS WHICH AFFECT THE SEMAPHORES.
TO REDUCE CONFUSION I HAVE ALSO SUBMITTED THE MATERIAL IN
[364,26] WHICH HAS INSTRUCTIONS (IN SEMINFO.DOC) AND FILES FOR
IMPLEMENTING SEMAPHORES IN RSX-11M-PLUS-V2.1.
 
I HAVE NOT RECEIVED RSX-11M-V4.1 AS OF THIS DATE SO I DON'T
KNOW WHAT CHANGES MAY BE REQUIRED TO ADD THE SEMAPHORES TO IT.
