what's wrong with this command

[adibzo]

exec [file nativename "c:/WINNT/system32/cmd.exe /c start "]

I am trying to launch a shell to run a telnet within from an tcl command but i am failing to execute the /c start part
i get the following error
exec return: "couldn't execute "c:\WINNT\system32\cmd.exe \c start ": invalid argument"
thanks in advance

The command [file nativename] gets a standard file name and returns a file name adapted to the underlying OS.
The /c and start arguments are arguments for the [exec] command, not the [file] command.
Try:

  exec [file nativename "c:/WINNT/system32/cmd.exe"] /c start

In fact, exec does the job for you and you don't need in this case [file nativename]. And because cmd.exe is on the standard path you can code:

  exec cmd /c start

HTH
