Thank you very much for the assistance.  I suspect Easypose may be best for my purposes. Sadly, even the 20ft rope only has around 100 segments. I shall contact the author ask if he has one with more.

I appreciate TrekkieGrrrl's reminder that rope is "very easy to model and rig". Sadly, I lack the skill and knowledge. Even the 'setup room' fills me with horror and confusion.

Phil's 'AllTiedUp' looks alot of fun to use, but rather more powerful than I currently need.

randym77's referred to the general difficulty of posing rope. I agree; and made harder if the rope is to be tightened and tied - in an animation.

Thank you all, again.
