*DECK NXT
SUBROUTINE NXT(NENTRY,HENTRY,IENTRY,JENTRY,KENTRY)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Module used to analyze and track a geometry data structure based
* on the new EXCELL type procedure.
*
*Copyright:
* Copyright (C) 2005 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):
* G. Marleau
*
*Parameters: input
* NENTRY number of data structures transfered to this module.
* HENTRY name of the data structures.
* IENTRY data structure type where:
* =1 for LCM memory object;
* =2 for XSM file;
* =3 for sequential binary file;
* =4 for sequential ASCII file.
* JENTRY access permission for the data structure where:
* =0 for a data structure in creation mode;
* =1 for a data structure in modifications mode;
* =2 for a data structure in read-only mode.
* KENTRY data structure pointer.
*
*Reference:
* G. Marleau,
* New Geometries Processing in DRAGON: The NXT: Module,
* Report IGE-260, Polytechnique Montreal,
* Montreal, 2005.
*
*Comments:
* Instructions for the use of the NXT: module:
* Option 1 -- Analyze and optionnally track a basic geometry
* [ TRKFIL ] VOLTRK := NXT: GEOMETRY :: (nxtget) ;
* Option 2 -- Track a geometry already analyzed
* TRKFIL VOLTRK := NXT: VOLTRK :: (nxtget) ;
* where
* TRKFIL : sequential binary tracking file to be created
* VOLTRK : tracking data structure
* (signature L_TRACK)
* GEOMETRY : geometry data structure
* (signature L_GEOM)
* (nxtget) : Processing options
* (read from input using the NXTGET routine).
