Try to parse this code

if
   @runcommand = true

If not scroll down ;)


























The escape #{ works in string literals only, so you probably just

   if targetserver.include? "#{@myhostname <%23%7B@myhostname>}"


I have no idea however what you meant with *.include?* (just high
lightening, I guess).
