Re: [Gems-users] MessageBuffer

["Lei Yang" <lya755@xxxxxxxxxxxxxxxxxxxx>]

Does anybody know how to use MessageBuffer the way I described? I did a 
search on the list archive and couldn't find anything close. I think the 
GEMS author might know how to do it.  I'm stuck on this and really 
appreciate your comments!
Thanks in advance.
