' File.WriteContents writes contentes without CR LF
File.WriteContents(fileName, "Write line 1" + CRLF)
For i =  2 To 10
  ' File.AppendContents appends contentes with trailing CR LF
  File.AppendContents(fileName,"Append line " + i)
EndFor
File.WriteLine(fileName, 3, "Inset line 3")
File.WriteLine(fileName, 5, "Inset line 5")
