[Caml-list] Declaration

[Caml-list] Declaration

[Holger Schulz]

I've a question on declaration, I've a problem porting something from 
SML/NJ

In SML/Nj i'd declare

val x= "fgdsgh";

and than

let val x = 2
      val y = x+2
in y end;

The first declaration would overwrite the x which will be used in the 
declaration of y. I've look in the Ocaml manual but I only found 
examples with simultanous declaration like

let x ="dhshdjsa";;

let x =2 and y= x+2 in y;;

which of course delivers a type error, coss x isn't overwritten here. 
How the syntax for non-simultanous declaration?

Thanks

  let x = 2 in
  let y = x+2 in
  y;;

Okay. I´ve subscribed to the beginners list now. So I´d like to 
unsubscribe from this list, but all attempts failed. I did receive 
error messages only. Could please anyone tell me, how to unsubscribe 
from here?

Thanks
