Function argument
f#

Hello everbody, I want to build some kind of port scanner and am having a problem with following code:

let isOpen =
#do some scanning
true

let host subnet ip =
sprintf "%s.%d" subnet ip

let scan subnet port =
seq {1 .. 254}
|> Seq.filter (fun ip -> isOpen host(subnet ip) port)

There is a syntax problem in calling the host function. I've tried every combination I could think of but didn't succeed in making it running.

.

Code below, see also

let scan subnet port =

    |> Seq.filter (fun ip -> isOpen (host subnet ip) port)
