  Thanks for the suggestions etc - much appreciated - I now have the 
following code :-

     if RUBY_PLATFORM =~ /(win|w)32$/

     elseif RUBY_PLATFORM.downcase.include?("darwin")
      system("open","rep.htm")


Just wondering why you split the arguments here; you didn't for the 
others. Nothing wrong with it, of course, they both work—but I always try 
to be consistent.


     elseif RUBY_PLATFORM.downcase.include?("linux")
      system("xdg-open rep.htm")
     else
      alert("Report is in file rep.htm")
     end
  Of course I only have a vista machine - so I can't test it fully - but 
it's a start!


Looks fine. One comment about ".downcase.include?"… although this may be 
clearer to non-rubyists, I would opt for a regexp. Shorter.


RUBY_PLATFORM =~ /w(in)?32$/i
RUBY_PLATFORM =~ /darwin$/i
RUBY_PLATFORM =~ /linux$/i

  Thanks

    Roger,
    Â It's kind of obvious when you think about it, that RUBY_PLATFORM only 

    displays the platform you are running on. It faithfully reported your
    platform. On my system,


    > ccoupe@twb:~$ irb
    > irb(main):001:0> RUBY_PLATFORM
    > => "x86_64-linux"

    It would be something different for a 32 bit linux. And somehing different
    for the flavors of OSX.


    Â Assuming you have a case RUBY_PLATFROM statement with when cases that 

    use regexps to match, then Linux needs to call 'gnome-open
    <your.html.file>'


  xdg-open is far more universal.
  Â 
    I can't speak for recent OSX but it used to be 'open
    <your.html.file>'



  Still is.
