*DECK TRIVAA
SUBROUTINE TRIVAA(NENTRY,HENTRY,IENTRY,JENTRY,KENTRY)
*
*-----------------------------------------------------------------------
*
*Purpose:
* TRIVAC type (3-D and ADI) system matrix assembly operator.
*
*Copyright:
* Copyright (C) 2002 Ecole Polytechnique de Montreal
* This library is free software; you can redistribute it and/or
* modify it under the terms of the GNU Lesser General Public
* License as published by the Free Software Foundation; either
* version 2.1 of the License, or (at your option) any later version
*
*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 or modification type(L_SYSTEM);
* HENTRY(2): read-only type(L_MACROLIB) (unperturbed);
* HENTRY(3): read-only type(L_TRACK);
* HENTRY(4): optional read-only type(L_MACROLIB) (perturbed).
* 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.
*
*Comments:
* The TRIVAA: calling specifications are:
* SYST := TRIVAA: [ SYST ] MACRO TRACK [ DMACRO ] :: (trivaa\_data) ;
* where
* SYST : name of the \emph{lcm} object (type L\_SYSTEM) containing the
* system matrices. If SYST appears on the RHS, the system matrices
* previously stored in SYST are kept.
* MACRO : name of the \emph{lcm} object (type L\_MACROLIB) containing the
* macroscopic cross sections and diffusion coefficients.
* TRACK : name of the \emph{lcm} object (type L\_TRIVAC) containing the
* TRIVAC \emph{tracking}.
* DMACRO : name of the \emph{lcm} object (type L\_MACROLIB) containing
* derivatives or perturbations of the macroscopic cross sections and
* diffusion coefficients. If DMACRO is given, only the derivatives or
* perturbations of the system matrices are computed.
* trivaa\_data : structure containing the data to module TRIVAA:
