There is always a class-like method here: http://jean-marc.duro.pagesperso-orange.fr/non-oop_demo.zip

include std/datetime.e 
include std/console.e 
include classes.e 
 
------------------------------------------------------------------------------ 
 
function get_years(atom secs) 
  atom days = floor(secs/86400) 
  return floor(days/365.25) 
end function 
 
------------------------------------------------------------------------------ 
 
function describe(integer entityID, sequence params) 
  atom secs = diff(getProperty(entityID, "birth_date"), now()) 
  printf(1, "\nHello! I speak %s.\n", {getProperty(entityID, "mother_tongue")}) 
  if length(params) then 
    printf(1, "I am %d years old. I was born in %s (%s).\n", {get_years(secs), getProperty(entityID, "birth_place"), params[1]}) 
  else 
    printf(1, "I am %d years old. I was born in %s.\n", {get_years(secs), getProperty(entityID, "birth_place")}) 
  end if 
  return 0 
end function 
 
------------------------------------------------------------------------------ 
 
procedure main(sequence cmd) 
  object void 
  integer TPerson = class("TPerson") 
 
  addProperty(TPerson, "birth_date", now()) 
  addProperty(TPerson, "birth_place", "") 
  addProperty(TPerson, "mother_tongue", "") 
  addMethod(TPerson, "describe", routine_id("describe")) 
 
  integer englishman = classes:new(TPerson) 
  setProperty(englishman, "birth_date", datetime:new(2010, 5, 14)) 
  setProperty(englishman, "birth_place", "Liverpool") 
  setProperty(englishman, "mother_tongue", "english") 
 
  integer frenchman = classes:new(TPerson) 
  setProperty(frenchman, "birth_date", datetime:new(1960, 8, 10)) 
  setProperty(frenchman, "birth_place", "Thionville") 
  setProperty(frenchman, "mother_tongue", "french") 
 
  integer german = classes:new(TPerson) 
  setProperty(german, "birth_date", datetime:new(1993, 2, 23)) 
  setProperty(german, "birth_place", "Munich") 
  setProperty(german, "mother_tongue", "german") 
 
  void = callMethod(englishman, "describe", {"Merseyside"}) 
  void = callMethod(frenchman, "describe", {"Lorraine"}) 
  void = callMethod(german, "describe", {"Bavaria"}) 
end procedure  -- main

main(command_line()) 
maybe_any_key() 

Do you mean something else ?
