           *** TABLES IN MIDAS ***

 TABLE files (.tbl) are used in MIDAS to operate on set of scalars
 arranged by columns of equal type of information.

  COMPUTE/TABLE   COMPUTE/REGRE   COMPUTE/HISTO   CONVERT/TABLE   COPY/TABLE
  COPY/xT         COPY/Tx where x = K,I or T      CREATE/COLUMN   CREATE/ROW
  CREATE/TABLE    CREATE/VIRTUAL  DELETE/COLUMN   DELETE/ROW      DELETE/TABLE        
  EDIT/TABLE      GET/xxx         IDENTIFY/xxx  where x=CURS, GCURS
  INTERPOLATE/xy where x and y = I,T              JOIN/TABLE
  LOAD/TABLE      MERGE/TABLE     NAME/COLUMN     OVERPLOT/HISTO  OVERPLOT/TABLE
  PLOT/HISTO      PLOT/TABLE      PRINT/HISTO     PRINT/TABLE     PROJECT/TABLE
  READ/HISTO      READ/TABLE      REGRES/LINEAR   REGRES/POLY     SAVE/REGRE
  SELECT/TABLE    SET/REFC        SHOW/TABLE      SORT/TABLE      STAT/TABLE
  TUTORIAL/TABLE  WRITE/TABLE

 You will also find TABLE related commands which are:
  
  -- dealing with fitting operations    : FIT/TABLE COMPUTE/FIT COMPUTE/FUNC
  -- dealing with multivariate analysis : commands from the context mva
  -- dealing with statistical analysis  : commands from the context statist

 For more information enter HELP XXXX/YYY (XXXX  command, YYY qualifier)

 Important:
 Most of the commands modifying a table will update its descriptor HISTORY.
 Since the length of this descriptor is limited, if you are doing a lot
 of operations on the same table, it may be better to turn off the automatic
 addition of history_lines. This can be done by adding an integer descriptor
 named HISTORY_UPDA to the table and setting it to 0.
