# Page n - Formatting using numbered positional arguments
At the end of the section, I say, "The `Write`, `WriteLine`, and `Format` methods can have up to four numbered arguments, named `arg0`,
`arg1`, `arg2`, and `arg3`. If you need to pass more than four values, then you cannot name them, as shown in the following code:"
At the end of the section, I say, "The `Write`, `WriteLine`, and `Format` methods can have up to four numbered arguments, named `arg0`, `arg1`, `arg2`, and `arg3`."
But the methods can only have up to *three* named arguments. I should have said, "The `Write`, `WriteLine`, and `Format` methods can have up to three numbered arguments, named `arg0`, `arg1`, and `arg2`. If you need to pass more than three values, then you cannot name the arguments using `arg0` and so on, as shown in the following code:"
```cs
// Four parameter values can use named arguments.
Console.WriteLine(
format: "{0} {1} lived in {2}, {3}.",
arg0: "Roger", arg1: "Cevung",
arg2: "Stockholm", arg3: "Sweden");
// Five or more parameter values cannot use named arguments.
Console.WriteLine(
format: "{0} {1} lived in {2}, {3} and worked in the {4} team at {5}.",
"Roger", "Cevung", "Stockholm", "Sweden", "Education", "Optimizely");
