c     These are the parameters which set up arrays for the calculation
c      of eigenvectors.  Note that eigenvectors are not needed for all
c      calculations, in which case you should set meigen = mpress = 0.

c=======================================================================
c
c     If you are going to do a pressure calculation, set mpress = 1.
c      Otherwise, you can set mpress = 0 to make the size of the
c      eigenvector matrix in bande small.  This will be useful only
c      for large atom calculations.  The program should catch any
c      inconsistencies (e.g., asking for pressure but setting
c      mpress = 0)
c
      parameter (mpress = 0)
c
c     Certain calculations, particularly the charge-density decompostion
c      calculations for QLMT runs, require knowledge of the individual
c      eigenstates.  Set meigen = 1 if you need this, meigen = 0 if you
c      don't.  The program should refuse to run if meigen is set wrong.
c      Note that pressure calculations need the eigenstates, hence
c      both meigen and mpress must be 1 if you want the pressure.

c
c     Though you may want to change some of the parameters below
c      the recommended vaules are good ones for most problems.  Please
c      do not change anything below this line unless you have a good
c      reason.
c
c     Note that the parameters defined here assume the definition of
c      other parameters in the P1 file.
c
c     mhe is the dimension of the eigenvectors for use in things like
c      orbital decomposition of the eigenstates.  If not needed,
c      (meigen = 0 above) we want to make this as small as possible.
c      The following trick should do it, without making compilation
c      difficult or machine dependent:
c
      parameter (mhe = meigen*mbas*(matom-1) + mbas)
c
c     Similar calculation for pressure:
c
      parameter (mhp = mpress*mbas*(matom-1) + mbas)
