I didn't ry it to be honest, the real problem was that the data (when 
exported by another tool), has (\n) line endings at arbitrary places (ie 
3 in a typical 'line' of data).  So I really wanted to strip them out 
before resplitting on the real line delimiter ';'.  I actually worked it 
out, I was trying filename.to_s.gsub!(/\n/, ''), but although ruby won't 
complain about this, it won't operate on it, if instead I spli on my 
delimiter ';' and then do a line.gsub!(/\n/,'') everything works fine

Thanks for the help

Is the idiom above more for processing multiple files (for each file, 
for each line do some processing close) kind of thing?
