Eval Buffer with ARGV

RubyWin can run script with argument(ARGV). Input Ruby1 MDI child window:

ARGV.each do |fname|
  puts "\n----- " + fname + "-----\n"
  File.foreach(fname) do |line|
    puts line
  end
end

Input file name in ARGV dialog, for example 'README INSTALL'.

Input on IRB chile window:

str = "Hello World"
str.sub("Hello", "Good Morning")
