> Why in ada, there is a separation between functions and procedures?

With a function you typically query some information without changing anything; with a procedure you execute something, usually with a change. E.g.

   function Target_Start (Control : Editor_Type) return Position;
   procedure Target_Start (Control : in out Editor_Type; pos : Position);

> Is there any real value in this?
It is very practical to spot - especially in a large package - where are the functions and where are the procedures.
