   Pair zero is a dummy pair interaction useful for requiring a
   force cutoff distance in the absense of pair-interactions or
   with hybrid/overlay if a larger force cutoff distance is required.

   This can be used in conjunction with bond/create to create bonds
   that are longer than the cutoff of a given force field, or to
   calculate radial distribution functions for models without
   pair interactions.

/* ERROR/WARNING messages:

E: Illegal ... command

Self-explanatory.  Check the input script syntax and compare to the
documentation for the command.  You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.

E: Incorrect args for pair coefficients

Self-explanatory.  Check the input script or data file.

E: Pair cutoff < Respa interior cutoff

One or more pairwise cutoffs are too short to use with the specified
rRESPA cutoffs.
