Subject: [ruby-talk:27371] Selecting class based on external information

Howdy,

I'm trying to select the class for an instance variable based on external
information and cannot figure out how. For example:

   class Host
      # variables and routines common to all hosts, default values for
      # OS specific things
   end
   
   class SunOS < Host
      # overrides for OS specific things
   end 
   
   # main routine would do this...
   
   OSname = `/bin/uname -s`.chomp
   
   myHost = OSname.new # on a Solaris system this should
                       # be equivalent to doing "myHost = SunOS.new"

The initialization of "myHost" is where I run into trouble. I can not figure
out how to do this. I'm sure Ruby has some "magic" to get this done, but
it's beyond me ... 

Jeff.
