Dear Monks,

Here's a question I'd like to solve in Perl :

Any tips welcome for changing this formating (generation ordered http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_dbag/dotdimb.htm#dotdimb1060220) :

gen2    gen3    gen4    gen5    gen6
A    B    C    D    E

into this one (recursively ordered http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_dbag/dotdimb.htm#dotdimb1060462) :

Parent    Child
    A
A    B
B    C
C    D

My question/problem is how do I "navigate" between tab separated columns using Perl, how getting dynamically next or previous columns ... hmm array is the key it seems but then how to permute making it recursive!

Many thanks for guidance.

SRx
