    This operator has several functions depending on the data. 

   --------------
   | Function 1 |
   --------------

    It enables the extraction of elements of different types
 from a given mesh GEO2. The result is a MAILLAGE or POINT type
 object.

    GEO1 = GEO2 ELEM | (type of element if several types)  | | LENTI1 |;
                     | COUL1                               | | N1     |;
                     |                                     |
                     |
                     | 'CONTENANT'  POIN1 ('TOUS') ('NOVERIF') ;
                     | 'APPUYE'  ( |'STRICTEMENT' | ) GEO3 ('NOVERIF') ;
                     |           ( |'LARGEMENT'   | ) 

                     |  'COMPRIS'  POIN1 POIN2 ;



    The different possibilities are the following :


   - the elements of the requested type are extracted from GEO2
     (MOT type).

   - the elements of the specified type whose list of numbers
     is in the LENTI1 object (LISTENTI type) are extracted.

   - the N1-ith element of the specified type is extracted.

   - the elements of the specified color COUL1 are extracted
     from GEO2.

   - the N1-ith element of the specified color COUL1 is extracted.

   - the elements of the specified color COUL1 whose list is in
     the LENTI1 object (LISTENTI type) are extracted.

   - the element of GEO2 containing the POIN1 point is extracted. 
     If the keyword TOUS is used, all elements containing POIN1 are 
     extracted. If the keyword NOVERIF is used, the operator may 
     create an empty MAILLAGE type result.

   - the elements of GEO2 lying strictly (by default) or broadly on
     the points of the GEO3 object (POINT or MAILLAGE type) are
     extracted. If the keyword NOVERIF is used, the operator may create 
     an empty MAILLAGE type result.

   - when GEO2 is a line, the 'COMP' keyword enables to extract a
     segment located between two points of the line. The segment 
     is described from POIN1 to POIN2 (type POINT).

    Examples :
    __________

                GEO1 ELEM TRI3
                GEO1 ELEM QUA4 3
                GEO1 ELEM APPUYE LARGEMENT POIN8
                GEO1 ELEM SEG2 (LECT 1 PAS 2 9)
                GEO1 ELEM ROSE
                GEO1 ELEM BLEU 1
                GEO1 ELEM TURQ (LECT 2 PAS 1 3)
                GEO1 ELEM CONT PO1
                LIG1 ELEM COMP PO1 PO2

  It is possible to specify simultaneously the type and the color

                GEO1 ELEM QUA4 ROSE
                GEO1 ELEM BLEU PRI6 4
                GEO1 ELEM SEG2 ROUG (LECT 1 PAS 2 9)


   --------------
   | Function 2 |
   --------------
    LMOT1 = GE02 ELEM 'TYPE' ;
    LMOT1 = GE02 ELEM 'COUL' ;

    It enables the user to get to know the types of elements contained
 in a given MAILLAGE (mesh) GEO2 ('TYPE' option),or the colours of the
 elements ('COUL' option). The result is therefore a LISTMOTS type object.

   --------------
   | Function 3 |
   --------------
                     |    'MAXI'           |           'AVEC'
   GEO1 = CHE1 ELEM  |    'MINI'           | ('ABS') (         LMOTS1 ) ;
                     |                     |           'SANS'
                     |'SUPERIEUR' |        |
                     |'EGSUPE'    |        |
                     |'EGALE'     | FLOT1  |
                     |'EGINFE'    |        |
                     |'INFERIEUR' |        |
                     |'DIFFERENT' |        |
                     |'COMPRIS' FLOT1 FLOT2|

   It enables the extraction from a field/element of the element(s)
 supporting the maximum or the minimum of the set of values of one
 or several components of the field or containing the values 
 verifying a relation of comparison with respect to a value of
 reference.

    CHE1     : MCHAML type object

   'ABS'     : key word indicating that the maximum or the minimum of 
               absolute values is requested

   LMOTS1    : LISTMOTS type object containing the names of the 
               components to be taken into account or to be excluded
               depending on whether the word 'AVEC' or 'SANS' is
               mentioned (if LMOTS1 is not specified, all the components
               will be taken into account)

     Note  : In the COMPRIS option, the boundaries FLOT1 and FLOT2 
     ________  are situated in the interval.
