Does this answer your question?

[gus@gusmac gus]$ cat tmp/exception.rb
#! /usr/bin/ruby

begin
   rand > 0.5 and raise "Hi from Murphy!"
   10.times do |i|
     begin
       i%2 == 0 and raise "Yack, #{i} is even"
     rescue => e
       puts("In loop exception: #{e.message}")
     end
   end
rescue => e
   puts("Setup failed: #{e.message}")
end
[gus@gusmac gus]$ ruby tmp/exception.rb
Setup failed: Hi from Murphy!
[gus@gusmac gus]$ ruby tmp/exception.rb
In loop exception: Yack, 0 is even
In loop exception: Yack, 2 is even
In loop exception: Yack, 4 is even
In loop exception: Yack, 6 is even
In loop exception: Yack, 8 is even
