[Gnuplot-info] Two questions on "here docs"

[Philipp K. J. <ja...@ie...>]

I am trying to understand gnuplot's new
"here doc" feature:

$data << EOD
1
2
3
EOD

plot $data

Questions:
1) Are there other ways to get data into these
  data structures, besides typing it in at the
  cmd prompt? For instance, is there a way to 
  read the data from a file?
2) Is there a preferred way to save the contents 
  of the data structure to file? I can do it using:
	set table "data.txt"; plot $d; unset table
  Is this the right way to think about this?

Best,
