*Purpose:
* Calculation of the discontinuity factors in a 1D reflector model.

*Author(s): A. Hebert
*
*Parameters: input/output
* NENTRY number of LCM objects or files used by the operator.
* HENTRY name of each LCM object or file:
* HENTRY(1): create type(L_GEOM) nodal geometry;
* HENTRY(2): create type(L_MACROLIB) nodal macrolib;
* HENTRY(3): read-only type(L_GEOM) sn geometry;
* HENTRY(4): read-only type(L_EDITION) sn edition.
* IENTRY type of each LCM object or file:
* =1 LCM memory object; =2 XSM file; =3 sequential binary file;
* =4 sequential ascii file.
* JENTRY access of each LCM object or file:
* =0 the LCM object or file is created;
* =1 the LCM object or file is open for modifications;
* =2 the LCM object or file is open in read-only mode.
* KENTRY LCM object address or file unit number.
