              DTA - Disk Transfer Area  (partially undocumented)

       DTA contains data, of which the first 21 bytes (00-15h) are known
       as being "reserved for DOS use on subsequent find next calls"

    Offset Size           Description

       00   byte       attribute of search (undocumented)
       01   byte       drive used in search  (undocumented)
       02  11bytes     search name used (undocumented)
       0D   word       directory entry number (0 based, DOS 3.x+, undoc.)
       0F   word       starting cluster number of current directory
                       zero for root directory (DOS 3.x+, undocumented)
       11   word       reserved (undocumented)
       13   word       starting cluster number of current directory
                       zero for root directory (DOS 2.x+, undocumented)
       15   byte       attribute of matching file
       16   word       file time  (see FILE ATTRIBUTES)
       18   word       file date  (see FILE ATTRIBUTES)
       1A   word       file size
       1E 13bytes      ASCIIZ filename and extension in the form NAME.EXT
                       with blanks stripped


       - fields of DTA change dependent upon function call in progress
       - the DTA cannot span a 64K segment boundary
       - for compatibility with CP/M the default DTA is at offset 80h
         in the PSP;  this area is also used for the command tail. To
         avoid collision, set another DTA (INT 21,1A) or preserve the
         command tail before using FCB function calls

       - see  INT 21,4E  INT 21,1A  INT 21,2F
