system() does whatever the underlying C compiler semantics do. Under UNIX
it does launch a shell in which to execute
the command you give it. Under DOS and Windows it generally doesn't do
that, but you can generally do it yourself via
system("command /C dir") or maybe system("cmd /C dir"). Bottom line: there
is no dir.exe, it is an "internal command"
within command.com or cmd.exe but those executables usually have a way to
invoke a single command (/C) and by the
way, we don't want to change Unicon system() to always invoke an Windows
shell in order to do system(), but
I can almost see special-casing the internal commands so that the cmd /C
stuff is automatically prepended.

Oh, wait, system should be running a shell, no? I haven't used the
windows or msdos version in years, so I don't know.
