 The `reread` command causes the current `gnuplot` (Note: gnuplot ) command
 file, as specified by a `load` (Note: load ) command or on the command line,
 to be reset to its starting point before further commands are read from
 it.  This essentially implements an endless loop of the commands from the
 beginning of the command file to the `reread` command.  (But this is not
 necessarily a disaster---`reread` can be very useful when used in conjunction
 with `if` (Note: if ).  See if for details.) The `reread` command has no
 effect if input from standard input.

 Examples:

 Suppose the file "looper" contains the commands
       a=a+1
       plot sin(x*a)
       pause -1
       if(a<5) reread
 and from within `gnuplot` you submit the commands
       a=0
       load 'looper'
 The result will be four plots (separated by the `pause` (Note: pause )
 message).

 Suppose the file "data" contains six columns of numbers with a total yrange
 from 0 to 10; the first is x and the next are five different functions of x.
 Suppose also that the file "plotter" contains the commands
       c_p = c_p+1
       plot "$0" using 1:c_p with lines linetype c_p
       if(c_p <  n_p) reread
 and from within `gnuplot` you submit the commands
       n_p=6
       c_p=1
       set nokey
       set yrange [0:10]
       set multiplot
       call 'plotter' 'data'
       set nomultiplot
 The result is a single graph consisting of five plots.  The yrange must be
 set explicitly to guarantee that the five separate graphs (drawn on top of
 each other in multiplot mode) will have exactly the same axes.  The linetype
 must be specified; otherwise all the plots would be drawn with the same type.
