Save the following code in a program (.prg) file and then run the program:

  SET TALK ON
  SET SAFETY OFF
  LOCAL xrec_cnt

  CREATE CURSOR av_tbl ( fld_01 C(2))

  FOR xrec_cnt = 1 TO 13316
     INSERT INTO av_tbl ( fld_01 ) VALUES (SPACE(2) )
  ENDFOR

  INDEX ON fld_01 TAG key_field

  INDEX ON fld_01 TAG key_field
