• add squared values
  Suppose we have a reference ASCIItable containing data to which we want to add the squared values of column » y «.

  2 head
  # reference ASCIItable
  x y
  1 1
  2 3
  3 4
  

  The lookup table contains

  2 head
  # lookup ASCIItable
  value squared
  1      1
  2      4
  3      9
  4     16
  5     25
  

  
  

  >  addLinked --link y value --asciitable lookup --label squared < reference
  

  yields

  3 head
  # reference ASCIItable
  # addLinked --index y value --asciitable lookup --label squared
  x y squared
  1 1 1
  2 3 9
  3 4 16
