Hi all,

I've written some code that I'm trying to test. I already know the code works because I went in and typed it directly into the F# interactive console. Here is the code in question:

(* determines if x is a member of Set S.
   It does this by comparing x to each member
   of S until it reaches the end. If it reaches
   the end - it is not a member
*)
let rec memberof = function
   | (x,[]) -> false 
   | (x,h::S) -> if x = h then true else memberof (x,S)

(* This function takes two Sets: S1 & S2
   S2 is added onto S1 one member at a time.
   For every member of S2 - it checks to see if 
   the equivelant value is already in S1. If it
   is not - the value is added. Otherwise, it is
   not added. This continues until all members are
   added.
*)
let rec union = function
   | (S1,[]) -> S1
   | (S1,h::S2) ->
        if not (memberof(h,S1)) then union((S1 @ [h]),S2) 
        else union(S1,S2)
 

(* This function takes two Sets: S1 & S2
   It compares the values of S1 & S2 and returns
   a new set that is composed of all the members
   found in both S1 & S2
*)
let rec intersection = function
   | (S1,[]) -> []
   | (S1,h::S2) -> 
        if (memberof(h,S1)) then ([h] @ (intersection(S1,S2)))
        else intersection (S1,S2)

This is all in my file "c:\functions.fs". Anyways, I want to load this into the F# Interactive Console from the file. I've tried to use #use & #load but I haven't had any luck. When I use #use it says "Unexpected Keyword 'let' or 'use' in directive." I then tried to just use use but then I got the error "Unexpected Incomplete Structured Construct At Or Before This Point" and it points to the two semi-colons at the end of the statement. I typed it in as #use @"c:\functions.fs";; and #use "c:\functions.fs";; (and again both times w/o the pound sign) but it only gives me an error. I tried to look at the #help;; but the #use command wasn't even in there.

I then tried the #load command, and it seemed to work. I typed it in as #load @"c:\functions.fs" and then it would spit out the name of a namespace (eg. FSI_0004) and then list all the files functions. All seems well - but when I try to then use the functions - it can never find them. I tried just typing in the function names and also using it like so: FSI_0004.memberof(0,l);; but it can't find the function.

I don't know if it matters - but I'm using the latest F# compiler, the Microsoft F#, September 2008 Community Technology Preview. That right there could be the problem. So if I can't figure it out in the next day or so I'm going to download the previous version.

Any and all help is very much appreciated
