Functions such as List.map are called aggregate operators, and they re powerful constructs, especially when combined with the other features of F#. Here is a longer example that uses the aggregate operators Array.filter and List.map to count the number of URL links in an HTML page and then collects stats on a group of pages (this sample uses the function http defined in 2): let delimiters = [| ' '; '\n'; '\t'; '<'; '>'; '=' |] let getWords (s: string) = s.Split delimiters let getStats site = let url = "http://" + site let html = http url let hwords = html |> getWords let hrefs = html |> getWords |> Array.filter (fun s -> s = "href") (site,html.Length, hwords.Length, hrefs.Length)

However, man pages are often technical and designed for experienced Ubuntu users who understand the terminology.

'execute query Dim rdr As SqlDataReader = cmd.ExecuteReader While (rdr.Read) Console.WriteLine("Employee name: {0} {1}", _ rdr.GetValue(0), rdr.GetValue(1)) End While The SqlDataReader object has a Read method that gets each row in turn and a GetValue method that gets the value of a column in the row. The particular column whose value it retrieves is given by the integer parameter indicating the index of the column. Note that GetValue uses a zero-based index, so the first column is column 0, the second column is column 1, and so on. Since the query asked for two columns, FirstName and LastName, these are the columns numbered 0 and 1 in this query result.
