*DECK LDRGEO
LOGICAL FUNCTION LDRGEO(IPGEOM,GEON1,GEON2,IMPX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Compare two sub-geometries stored on LCM (do not compare mixture
* numbers).
*
*Copyright:

* version 2.1 of the License, or (at your option) any later version
*
*Author(s): A. Hebert
*
*Parameters: input
* IPGEOM pointer to the geometry (L_GEOM signature).
* GEON1 name of the first sub-geometry.
* GEON2 name of the second sub-geometry.
* IMPX print flag (impx=0 for no print).
*
*Parameters: output
* LDRGEO equality flag (=.true. if the two geometries are identical).
