beginners list

[christian konrad <konrad@in.tum.de>]

Hello again,

I just signed up to the beginners with the message: "/Your membership to 
the ocaml_beginners mailing list is waiting for the moderator's approval."
/so for a last time I misuse this list, sorry. I wrote this piece of code:

type ergebnis = {teamid1: int; teamid2: int; goals1: int; goals2: int};;
type spieltag = {number: int; ergebnisse: ergebnis list};;

...

let rec readSpieltagelist filehandle numberofgames =
    let createErgebnis tid1 tid2 g1 g2 =
        {teamid1=tid1; teamid2=tid2; goals1=g1; goals2=g2;}
    in
    let rec readErgebnisse fh number =
        match number with
        | 0 -> []
        | n -> let line = (input_line fh) in (Scanf.sscanf line 
"%d\t%d\t%d\t%d" createErgebnis):: (readErgebnisse fh (number-1));
    in
    try
        let spieltag = int_of_string(read_line filehandle) in
        let ergebnislist = (readErgebnisse filehandle numberofgames) in
        {number=spieltag; ergebnisse=ergebnislist;} :: 
(readSpieltagelist filehandle numberofgames);   
    with End_of_file -> [];;

with the hope to read from a file informations like:
1
1   2   3   4
3   2   1   6
4   2   1   9
2
1   4   9   2
3   2   1   9
9   1   2   3
3
...

I would call: readSpieltagelist filehandle 3
in that case.
This code doesn't compile, I get an error with the variable filehandle 
in this expression:

        let ergebnislist = (readErgebnisse filehandle numberofgames) in

"This expression has type unit but is here used with type in_channel"


Why that?? I really do not understand that. Do I use "filehandle" 
somewhere as a unit type? Where, why?


Thanks for help,
chris
