Subject: Re: [Jprogramming] Formatting tables

For higher dimensional arrays I use to_literal which builds a vector with line 
feeds to look as though j displayed it. This is suitable for transfer to file.  
For gnuplot two successive blank lines separate the index groups.

    rank =: #@:$
    to_literal=: ([:,/,.&LF)"2^:(0>.<:@:rank)@:":  NB. as a dyad x is x of ":
    to_literal i. 2 3 4
  0  1  2  3
  4  5  6  7
  8  9 10 11

12 13 14 15
16 17 18 19
20 21 22 23


    $ to_literal i. 2 3 4
74
