  call-by-value-result
  
     An argument passing convention where the actual argument is
     a variable V whose value is copied to a local variable L
     inside the called function or procedure.  If the procedure
     modifies L, these changes will not affect V, which may also be
     in scope inside the procedure, until the procedure returns
     when the final value of L is copied to V.  Under
     call-by-reference changes to L would affect V immediately.
     Used, for example, by BBC BASIC V on the Acorn
     Archimedes.
