Subject: Re: why i can't get the value out of each block?

Hi

In that case, x has scope of inside block.
if you want to reffer x out of blok, sould initialize before block.
like berow.

a=[1,2,0,10]
x=nil
a.each_with_index {|item, idx|
  begin
  puts 10 / item
  rescue
  print "it is my wrong ",item,idx,"\n"
  x=item
  end}
puts "x=",x
