There are at least two possibilities.  The specialised one is to look at
the help for save() and notice that you can specify a vector of names of
objects with the list= argument
  save(list=x,file=nnam)

The more general one is to use substitute() or do.call(). For example
  do.call("save",list(as.name(x),file=nnam))
