Should We Say That F# Employs Good IO Methods?

@ntwilson

you could just leave Results as an int:

open System

let list = [1;2;3]
let target = 2
let mutable Results = -1
list |> List.iteri (fun i obj → if obj = target then Results ← i + 1 )

let d = Results
let list2 = [“A”;“B”;“C”;]
let mutable e = String.Empty
list2 |> List.iteri (fun i obj → if i = d then
let f = sprintf “%d %A” i obj
e ← f )

printf “%s” e

Totally kick@#$!!! I chose to go with your second solution modified if statement i=d to i=(d-1) for calibrating purposes and excluded %d and i from its sprintf for accuracy. Thanks ntwilson! I’m tabbing your terms as completely solved.
