This group discusses Rails, not raw Ruby. You’d get better answers on
the ruby
newsgroup/mailing list/thing.

And I would just use YAML::load to read the file, and let YAML do all
that
low-level parsing and representing.

This is how you can do it:

ar = []
ha = {}
IO.foreach(“book_list.txt”) do |line|
catalog=line.chomp.split(",")
products.store(items[0].to_i,
[catalog[1],catalog[2].to_i,catalog[3].to_i)

To array

ar << catalog

To Hash

ha[‘some_key’] = catalog
end

It can be done as oneliner:
ar=[]
File.readlines(“book_list.txt”).each {|line| ar <<
line.chomp.split(",")}
