Subject: Re: severe newbie question (class, fixnum, array)

Three things:

a) it's to_s, as in @number.to_s
b) create the array and then insert an element to it:

thread = []
thread[1] = Thread.new 1

c) to create a file, you could (should?) use file.join, which will
create the path with the right separators, etc. Look for the rdoc for
File.join.
