Note that in Ada you have named parameter associations. The above is hardly 
readable, who remembers which is which. Use instead

   Put (Sum, Fore => ..., Aft => ..., Exp => ...);

But please do not exaggerate as some do by always writing

   P (X => X, Y => Y)

for all subprogram calls where the named association does not add any 
information. However

  arctan (X => X, Y => Y)

is a completely different beast. The definition has parameter Y first, X second 
(for good mathematical reasons), so if you simply write

  arctan (X, Y)

it's unclear whether you really meant

  arctan (X => X, Y => Y)

or

  arctan (X => Y, Y => X)

So always try to give as much information as possible by providing named 
associations. If actual parameter names already provide enough and types are 
different, there is no need to use named association.
