Int 21 Fn 16  - Dos 1+ - Create Or Truncate File Using Fcb                 [D]

   AH = 16h
   DS:DX -> unopened FCB (see #1034), wildcards not allowed

Return: AL = status
       00h successful
       FFh directory full or file exists and is read-only or locked

Notes: if file already exists, it is truncated to zero length
   if an extended FCB is used, the file is given the attribute in the
     FCB; this is how to create a volume label in the disk's root dir
   not supported by MS Windows 3.0 DOSX.EXE DOS extender
   (FAT32 drive) this function will only succeed for creating a volume
     label; FAT32 does not support FCBs for file I/O
