These system calls are not undocumented. See Microsoft's OEM documentation for MS-DOS version 2.x, or technical manuals published by Digital Equipment Corporation and Zenith for their microcomputers. Since these system calls were officially supported in version 2.x, and Microsoft has never announced that support is being dropped or advised people not to use them, you can probably safely assume that they are still official. -- Rahul Dhesi UUCP: oliveb!cirrusl!dhesi
