/* ERROR/WARNING messages:

E: Cannot dump sort when multiple procs write the dump file

UNDOCUMENTED

E: Cannot dump sort on atom IDs with no atom IDs defined

Self-explanatory.

E: Dump sort column is invalid

Self-explanatory.

E: Too many atoms to dump sort

Cannot sort when running with more than 2^31 atoms.

E: Too much per-proc info for dump

Number of local atoms times number of columns must fit in a 32-bit
integer for dump.

E: Cannot open gzipped file

LAMMPS was compiled without support for reading and writing gzipped
files through a pipeline to the gzip program with -DLAMMPS_GZIP.

E: Cannot open dump file

The specified file cannot be opened.  Check that the path and name are
correct. If the file is a compressed file, also check that the gzip
executable can be found and run.

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: Cannot use dump_modify fileper without % in dump file name

UNDOCUMENTED

E: Cannot use dump_modify nfile without % in dump file name

UNDOCUMENTED
