Re: [Caml-list] lablgtk newbie question

[Richard Jones <rich@annexia.org>]

More newbie questions ...

Below is my program so far.

It works, but it doesn't "look like" any of the example lablgtk
programs.  In particularly, I'm using a lot of ...

	let _ = ...

basically to execute an imperative statement. Perhaps this is a legacy
of the fact that I'm a very experienced imperative programmer.

I think I'm really confused about these:

let
let ... in
;
;;

Is there some good tutorial for this? My main reference is
http://caml.inria.fr/ocaml/htmlman/manual003.html but that doesn't
really explain these basics too well.

Comments & guidance welcome.

Rich.
