in thread reparse tree in textfile

Why set the length of the array only to change it immediately?

It was one way to do it. The goal was to keep @path with only "pure" node information, and not have redundancies like ".", "/", and previous nodes repeated as the indexes go higher.

I also hate the needless use of global vars.

Me too. But a data structure outside the loop was needed to oversee things.

That's unrelated. I was referring to $#a=...; push @a,...;. The first statement sets the size of the array. Then next changes it. Why not just set it to the right size right from the start.
