> Why didn't you show instead how to output arguments joined by a comma or some other separator instead of space. The Tcl variant to output "comma" as separator (note -- this is not "CSV"). puts [join $argv ,] If you wanted "comma space" you'd do: puts [join $argv ", "] If you actually wanted "CSV" then it would be (assuming tcllib is installed): package require csv puts [csv::join $argv]
