I'm going through the MS-DOS Encyclopedia by Ray Duncan -- but I can't find any reference to the system call to change the switch character... Anyone have the code and registers needed to write a small assembler program to change the switchar from "/" to "-". I did it years ago but can't find the reference materials.
