Re: How i can use a list in Caml Light language?

[Draculia]

In Caml light 07 
once that I have created a list:

# let lista= 3::9::4::7::6::5::8::[];; 
 
and I have inserted a new term (30)
 the answer of the compiler is

-: int list = [30;3;9;4;7;6;5;8]

why if I require the value of list doing

# lista;;

the answer is

-: int list = [3;9;4;7;6;5;8]

or rather the list Lista? 

The same with the function of cancellation!!

How I could create a function that given a list,
check that there are not 2 elements equal?

Please help me within febryary 10.

THANK YOU.

P.S.: Sorry for my english but i'm an italian boy
and my translator program is not good !

Among your many errors is the egregious one of posting a question entirely
about Caml to an Ada newsgroup. While I realize that there is a book in
French teaching programming using Caml and Ada, I see no Ada here. 

That said, Caml lists are immutable, so if you want a new list with "30" 
prepended, you'll have to say 

let listb = 30::lista;;

and use that. You can figure out the rest of your homework yourself. I 
suggest reading a very basic introduction to Caml, like
