    (CONF2) (CAR2)  = FORME  (CONF1) (CHPO1) (MOD1 CAR1) ;


    Description:
    ____________

    FORME manipulates the CONFIGURATION type objects (discretization
 fields). It has a double function : it can be an instruction 
 or an operator.


    Contents :
    __________

    As an instruction, FORME updates the coordinate fields from the
 CONFIGURATION CONF1 (or by default the current coordinates) which
 might have been updated by means of the displacement field CHPO1
 (CHPOINT type).

    As an operator, FORME creates the CONFIGURATION CONF2 containing
 the coordinate field updated by means of FORME and updates the coordinate
 fields from the new CONFIGURATION CONF2.

     In addition, some characteristics such as the vectors defining the local
 bases for the POUTRE, TUYAU, TUYAU FISSURE and LINESPRING elements may
 be updated (for the TUYAU FISSURE and LINESPRING elements, only small
 rotations are considered).
     
    In this case, the characteristic field CAR1 will have to be
 supplied (MCHAML type, CARACTERISTIQUES subtype) as well as the model
 of calculation MOD1 (MMODEL type) which will be updated in CAR2.
 As a result, it is compulsory to supply CHPOINT CHPO1.

    Example :
    _________

    DEP = RESOU RITOT FORCE ; --> computation of the displacement field
    FORME DEP               ; --> updating of the coordinate field 
    TRAC  GEO1              ; --> plot of the deformed structure 

    If GEO1 is the undeformed structure of the current problem, 
 the TRAC operator will supply the plot of the deformed structure
 without amplification.

    An alternative is:

    CONF1 = FORM ;   --> stores the initial configuration in CONF1
    CONF2 = FORM DEP1 ; --> changes to a new configuration stored in
                            CONF2
    TRAC GEO1 ;      --> plot of the deformed structure     
    FORM CONF1 ;     --> back to the initial configuration
