I have a table with the structure and data similar to listed below:
excent with about 500 entries

field1 field2 field3
A B .T.
B C cond2
B D cond3
C D .T.
B E cond1
E C .T.

I am trying to assemble a table or array that will include all possible paths

in this case the paths to d are
a->b->c->d
a->b->d
a->b->e->c->d
Any suggestions
Thanks in advance
