If this is the wrong list for this question, can you please let me know whish list I should go to.
My output should look something like this: a-\ |-b | | | \-c | | | \-d | | | | | \-g | | | \-e | |-f | | | \-h | | | \-I | | | \-j | | | \-k | | | \-l | \-m My data file has at least these two columns: Col1 Col2 a b a c b d c e c f a g d h f I f j i k i l k m a What is the best way to do this? I have been working with a while loop calling a subroutine that I am trying to shift and unshift the array. This has not worked so far. Tim
