@ -425,15 +425,15 @@ python-style variable can be used in place of an equal-style variable
anywhere in an input script, e.g. as an argument to another command
that allows for equal-style variables.
For the *timer* style no additional argument is specified. The value
of the variable is set by querying the current elapsed CPU time of the
simulation. This is done at the point in time the variable is defined
in the input script. If a second timer-style variable is also
defined, then a simple formula can be used to calculate the elapsed
time between the two timers, as in the example above. As mentioned
above, timer-style variables can be redefined elsewhere in the input
script, so the same pair of variables can be used in a loop or to time
a series of operations.
For the *timer* style no additional argument is specified. The value of

For the *internal* style a numeric value is provided. This value will
be assigned to the variable until a LAMMPS command sets it to a new
