*Author(s): A. Hebert
*
*Parameters: input
* IPDRL pointer to the draglib (L_DRAGLIB signature).
* NGRO number of energy groups.
* NL number of Legendre orders required in the calculation.
* NL=1 or higher.
* NDEL number of delayed precursor groups.
* NBESP number of energy-dependent fission spectra.
* SN dilution cross section in each energy group. A value of
* 1.0E10 is used for infinite dilution.

* normalization.
* NED number of extra vector edits.
* HVECT names of the extra vector edits.
* DELTA lethargy widths.
* LBIN number of fine groups.

* DELECC lethargy width of eccolib libraries.
* IGECCO number of equal-width lethargy groups with eccolib libraries.
* IMPX print flag.
*
*Parameters: input/output
* NGF number of fast groups without self-shielding.
* NGFR number of fast and resonance groups.
*
*Parameters: output
* LSCAT scattering mask (=.true. if a given Legendre order of the
* scattering cross section exists).
* LSIGF fission mask (=.true. if the isotope can fission).
* LADD additional cross section mask (=.true. if a given additional
* cross section exists).
* LGOLD Goldstein-Cohen mask (=.true. if Goldstein-Cohen parameters
* exists).
* SIGS scattering cross sections.
* SCAT scattering transfer matrices.
* TOTAL total cross sections.
* ZNPHI fluxes.
* SIGF nu*fission cross sections.
* CHI fission spectrum.
* CHI4G energy-dependent fission spectra.
* SADD additional cross sections.
* GOLD Goldstein-Cohen parameters.
* BIN BIN(IGR,1): total fine group cross sections;
* BIN(IGR,2): isotropic scattering fine group cross sections;
* BIN(IGR,3): nu*fission fine group cross sections.
