    CHAINE  ('FORMAT'  format ) OBJET1(?N) ( OBJET2  .....)  ;

                                   OBJETi=MOT,ENTIER,FLOTTANT

    Description :
    _____________

    The CHAINE operator enables the user to create a word 
  that does not exceed 72 characters.

    Contents :
    __________

    OBJETi : MOT, ENTIER or FLOTTANT type objects
    FORMAT : key word followed by a string , the FORTRAN format for
             following FLOTTANT .The default format is '(1P,E12.5)'.

    Note :
    ________

     The string is created by the concatenation of the strings 
 of the OBJETi objects of MOT type.
    
    If OBJETi is an ENTIER or FLOTTANT type object, it will be
 first converted into a string.

     *N or /N enables you to centre the object left or right
 on the Nith line.

    Example :
    _________

    PRESS = 25.86  ;
    ICAS  = 2 ;
    AA=CHAINE  ' CAS DE CHARGE NUMERO:' ICAS '  PRESSION :' PRESS;

 the above series of instructions creates the following word :

   CAS DE CHARGE NUMERO:2  PRESSION : 2.58600E+01


The instruction
    AA=CHAINE  ' CAS DE CHARGE NUMERO:' ICAS  FORMAT '(F6.2)'
             '  PRESSION :' PRESS;

    creates the following word :
   CAS DE CHARGE NUMERO:2  PRESSION : 25.86

  and the instructions
  F1='(F6.2)';
  BB= CHAINE ' PRES1=' FORMAT F1 PRESS ' PRES2=' PRESS ' PRES3='
        FORMAT '(SP,1PE10.3)' PRESS ;
  creates in BB :
   PRES1= 25.86 PRES2= 25.86 PRES3=+2.586E+01

    IJK=321; CC=CHAINE IJK*10 IJK*20;
            DD=CHAINE IJK/10 IJK/20;
    MESS CC ; MESS DD;

 The result is :
       321       321
         321       321
