Int 21 Fn 4F  - DOS 2+ - "findnext" - Find Next Matching File              [D]

   AH = 4Fh
   [DTA] = data block from previous FindFirst or FindNext call

Return: CF clear if successful
   CF set on error
       AX = error code (12h) (see AH=59h)

Note:  under Novell DOS 7, if the FindFirst call (AH=4Eh) had CX=0088h, then
     the next matching deleted file will be returned
BUG:   DR-DOS 3.41 and 5.0 return the Directory attribute for the volume label
