As Olivier points out the argument is what you would write on the console to run the command.

You can launch apps and other things using that instruction.

The "problem" is that it has been deprecated and that it is highly recommended to use the CreateProcess[^] function now...

Good luck...

[Led Mike tone] It is well hidden inside the documentation [/Led Mike tone]: system[^].

Not necessarily write to console. It would call CreateProcess, using reserved-fields of STARTUPINFO.
system function is nothing but simplified call for CreateProcess. It can, however, handle internal command.com/cmd.exe commands like 'cls', 'type' etc.

int system ( const char * command );
this is the argument for system().

The argument of this function is what you would write in a Console. The full list or available commands can be found there:
