That's presumably because cls is a builtin command to the XP shell, rather
than a separate executable; presumably the system command is trying and
failing to execute a program called "cls.exe". Instead, try passing cls to
the shell like this:
> call system('cmd.exe /c cls')
You'll probably also need to do the same for other commands such as 'cd'
or 'dir' if you ever want to use them in system calls.
BTW, I see you're using cygwin. That trick is also very useful in bash
shell: I have things like
alias cls='cmd /c cls'
alias start='cmd /c start '
in my .bashrc
Can't think of a witty .sigline today....
