as: Initialize nvar variable Non initialized variables in awk have the empty string value, that when it is used in a numerical context is evaluated to 0, but it is still evaluated to "" in the context of an array index. Nvar was used later to run over the arrays but 0 didn't have any content in the arrays because nvar evaluated to "" in the first iteration.
