SQLloader has direct support for the dBase (xBase) .DBF file format using the following syntax in the control file:

INFILE "DBFFILE.DBF" "DB3 xx"

where xx is the record length of the xBase file.

Example:

dBase III file name is RRUNOUT.DBF
  last update was on 1/5/94;
  there are 1 records in the file;
  the header length is 194 bytes;
  the record length is 93 bytes.
dbf field information:

Table name: RRUNOUT
  field name type length decimal

  1      RO_ECODE   C     1       0
  2      RO_EMSG    C     80      0
  3      RO_REPORTS N     2       0
  4      RO_PAGES   N     4       0
  5      RO_RIRECNO N     5       0

LOAD DATA
INFILE "RRUNOUT.DBF" "DB3 93"
APPEND
INTO TABLE RRUNOUT

   (RO_ECODE   POSITION(2:2) CHAR,
    RO_EMSG    POSITION(3:82) CHAR,
    RO_REPORTS POSITION(83:84) INTEGER EXTERNAL,
    RO_PAGES   POSITION(85:88) INTEGER EXTERNAL,
    RO_RIRECNO POSITION(89:93) INTEGER EXTERNAL)

If I remember correctly position(1:1) in each xBase record is reserved for the Tombstone marker.
