      SUBROUTINE SENGET(IPRINT,NL,NANIS)
*
*-----------------------------------------------------------------------

*
*Parameters: output
* IPRINT  print level.
* NL      Legendre contribution in scattering on library.
* NANIS   Legendre contribution in scattering for SENS:
*         = 1  only isotropic contribution; 
*         = ilana contribution up to ilana=NL considered
*         (default is ilana=1).
*
*Comments:
* Input data is of the form:
*    [ EDIT iprint ]
*    [ ANIS ilana ]
