int
system(cmd)
	char *cmd;
{
	if (cmd == "" || cmd == NULL)
		Execute("",Input(),0L);
	else
		Execute("",0L,0L);
	return(0);
}

Though I can't remember if you have to specify output as well in either
case.  Alternatively, you may want to return -1 if Execute fails, but
you can't tell if the command failed.
