    Operateur PROG                           Voir aussi : LECT
    --------------   
    LREEL1 = PROG 1. 2. 3. 4. 5. ;


    Description :
    ____________

    The PROG operator creates a LREEL1 object of LISTREEL type from
 an arbitrary number of ENTIER or FLOTTANT type objects.

    The PAS subinstruction is used to produce numbers spaced equally
 apart, and the * subinstruction is used to repeat a number. In 
 addition, options corresponding to some functions are available.

    Comments :
    _________

    ------------------------
    |  PAS subinstruction  |
    ------------------------

    LREEL1 = PROG 1. PAS 2. 5. ; amounts to : LREEL1 = PROG 1. 3. 5. ;

    If PAS does not split up the gap, the value to be taken into
 account is the closest one likely to do it.
    If PAS is incoherent, the result will contain the initial value
 and the final value.

    Other possibility :

  LREEL1 = PROG 1. PAS 2. NPAS 2 ; amounts to : LREEL1 = PROG 1. 3. 5. ;

    NPAS must be positive or null.


    -----------------------
    |  Subinstruction  *  |
    -----------------------

    LREEL1 = PROG 4 * 3. ; amounts to : LREEL1 = PROG 3. 3. 3. 3. ;

    Negative steps may be used simultaneously with subinstructions.

    LREEL1 = PROG 1. 2.  PAS -2. -6. 2.  3. * 9. PAS 2.  3. * 13. ;
or
    LREEL1 = PROG 1. 2.  PAS -2. NPAS 4  2.  3. * 9. PAS 2.  3. * 13. ;
amounts to
    LREEL1 = PROG 1. 2. 0. -2. -4. -6. 2.  9. 9. 9.  11. 13. 13. 13.;


    ------------------
    |  SINU  option  |
    ------------------

    LREEL1 = PROG 'SINU' FLOT1 ('PHAS' FLOT2)  ('AMPL' FLOT3)  ...

                ...         | PROG 1. 2. ..X.. 4. 5.  |    ;
                            | LREEL2                  |

    The SINU option for the PROG operator is used to produce a list of
 real numbers sine from  :

       - an arbitrary number of ENTIER or FLOTTANT type objects
       - a LISTREEL type object

    ( FLOT3 * SIN ( 360*FLOT1*X + FLOT2 ) ) is associated with X


    LREEL2  : LISTREEL type object

    FLOT1   : frequency in Hz (positive FLOTTANT type)

   'PHAS'   : key word followed by :
    FLOT2   : phase value in degrees (FLOTTANT type)
              equalling 0. by default.

   'AMPL'     key word followed by :
    FLOT3   : sine amplitude value (positive FLOTTANT type)  
              equalling 1. by default.

    Note :
    ________

    Of course, you may employ the PAS and * instructions for this
  option.


    ---------------------------------
    |  LINE , EXPO , LOGA  options  |
    ---------------------------------

                  |'LINE'|
    LREEL1 = PROG |'EXPO'| ('A' A1) ('B' B1) | PROG 1. 2. ..X.. 4. 5. |
                  |'LOGA'|                   | LREEL2                 |

    The 'LINE', 'EXPO' and 'LOGA' options calculate the values for 
 the following functions :

       A1*X+B1        for the 'LINE' option
       EXP(A1*X+B1)   for the 'EXPO' option
       LOG(A1*X+B1)   for the 'LOGA' option

 for the values of the X-variable contained in the LREEL2 object of 
 LISTREEL type or specified after the 'PROG' key word.

    LREEL2  : LISTREEL type object

   'A'      : key word followed by :
    A1      : value of FLOTTANT type, equalling 1. by default.

   'B'      : key word followed by :
    B1      : value of FLOTTANT type, equalling 0. by default.
