  But you can certainly have a set of subprograms with the same name
but differing number of parameters:
  procedure my_fun(s1 : in string) is ...
  procedure my_fun(s1,s2 : in string) is ...
  procedure my_fun(s1,s2,s3 : in string) is ...
  procedure my_fun(s1,s2,s3,s4 : in string) is ...
or you could use default values
  procedure my_fun(s1 : string;        -- require at least one parameter
                   s2 : string := "";
                   s3 : string := "";
                   s4 : string := "") is ..
