Not only it works, it's also  very nice:
thanks Hans.

(
I know that
/\newdimen\RightMarginWidth \RightMarginWidth=\rightmarginwidth
/it's strange (after all i use \footerheight at the next line...).

Some time ago i wrote something like
\/MyDimension/=0.87\/rightmarginwidth ///
During some corrections/enhancement  i made a mistake and i wrote
\/rightmarginwidth =0.87/\/MyDimension///

A nightmare.

When i feel insecure (will i use this dimensions as readonly or 
read/write variables ?)
i prefer a safe copy
(in this case i'm sure that i use \footerheight as a readonly var).
)
