Subject: Loop behavior not understood (newbie)

My coding looks like this:

===================================================================

detailedModel = File.open( "detailed_model", "r" )
detailedModelModified = File.open( "detailed_model_mod", "w" )
string = nil
flag = false
detailedModel.each_line do |line|
   if (flag == false)  ||  (line.lstrip =~ /^[\*]/) then
      detailedModelModified.puts line
      if (line.lstrip =~ /^(41)/) then
         flag = true
     next
      end
   end
end

===================================================================

When running Ruby 1.8.7 on Eclipse, this results in nothing being
printed to the detailed_model_mod file.  If I take out the if-end loop
trying to pattern match the string with the leading "41", then it prints
out fine.

What in the heck is going on here?  I've tried a number of different
things, and fail to understand this behavior.

Respectfully, TPL
