* R>DROP ( -- )

shortcut (e.g. in CSI-Forth)

note that the access to R is configuration dependent - only in
a traditional fig-forth each NEST will be one cell wide - in case that
there are no LOCALS| of course. And remember, the word above reads
like the sequence R> and DROP but that is not quite true.
 : R>DROP R> DROP ; ( is bad - correct might be )  : R>DROP R> R> DROP >R ;
