  Thanks Jim.  
  
  If so, the Editor's note "Define better what an invalid dword
means." should be removed from sub-clause 6.8.2.

~ Sriram,

~ The invalid dword in the DWS state machine is indeed the invalid dword

~ In sas-r03d.pdf sub-clause 6.8.2 there is a note that reads:
~ 
~ "Editor's Note 6: fill in this section. Define better what an invalid 
dword
~ 
~ means."
~ 
~ In the definitions section invalid dword is defined as follows:
~ 
~ "3.1.61 invalid dword: A dword with an illegal character, with a control
~ character in other than the first character position, with a control
~ character other than K28.5 or K28.3 in the first character position, or
~ with
~ a running disparity error."
~ 
~ Does this definition apply to the use of the term "invalid dword" in the
~ SP_DWS state machine description or does it only include dwords which have
~ control character in other than the first character position?
~ 
~ Please clarify.
~ 
~ thanks,
~ \Sriram\
