     I've noticed that although I may do a fflush (buffered I/O),
     or write, or _dos_write, the data is not always written out
     to file.

     On speaking with Miscrsoft, they informed me that the write
     may be committed by using INT 0x21, Function 0x68, on DOS 3.3
     or later.  Is there a way around this for earlier versions of
     dos, without opening and closing the file each time.

Yes, the classic solution for DOS is to first DUP the file handle code,
and then CLOSE the new handle.
