*DECK BIVSPS
SUBROUTINE BIVSPS(IPTRK,IPMACR,IPSYS,IMPX,NGRP,NEL,NLF,NANI,NBFIS,
1 NALBP,LDIFF,MAT,VOL,NBMIX)
*
*-----------------------------------------------------------------------
*
*Purpose:
* Recover the cross-section data in LCM object with pointer IPMACR,
* compute and store the corresponding system matrices for a simplified
* PN approximation.
*

*Author(s): A. Hebert
*
*Parameters: input
* IPTRK L_TRACK pointer to the bivac tracking information.
* IPMACR L_MACROLIB pointer to the cross sections.
* IPSYS L_SYSTEM pointer to system matrices.
* IMPX print parameter (equal to zero for no print).
* NGRP number of energy groups.
* NEL total number of finite elements.
* NLF number of Legendre orders for the flux (even number).
* NANI number of Legendre orders for the scattering cross sections.
* NBFIS number of fissionable isotopes.
* NALBP number of physical albedos per energy group.
* LDIFF flag set to .true. to use 1/3D as 'NTOT1' cross sections.
* MAT index-number of the mixture type assigned to each volume.
* VOL volumes.
* NBMIX total number of material mixtures in the macrolib.
