Hi another time :)
this seems more a chat program than a news group, we are very quickly :)

This is only to talk because my problem was solutioned with the lastest
messages.

>> Later when i execute
>> methods over this PERSON it will execute the "datos" method of WOMEN or
>> MAN depending of its subtype (that's polymorphism).
>

Thats ok. But you know that your object "is a" WOMEN or a MAN because:
1) you have created it "o=obj_new('WOMAN')" and then you know its
methods or
2) you request its type with OBJ_ISA() funtion and then need to know it
methos to invoque one.

I like the idea of use OBJ_ARR because i dont need to know the type of
object it containes (WOMEN or MAN) o only know that this objects are
PERSON's that has the method "datos". I can invoque that method on all
this and the "polymorphism" does the rest.

Anyway if you come to Spain int he future and goes to Barcelona, call me
and i invite you to have a beer, wine or a glass of watter if it is
necesary.

Thanks for your time and to be patient with fiker newbie :)
Bye.
