You can do

file.write "blah blah " +
       "and so on"

file.write "blah blah " \
       "and so on"


I myself use these rules of thumb to decide which method to use:

1. printing of text: puts, print, printf
2. output of binary or chunked data: write

E.g. for copying data from one file to another, I'd do

buffer = ""
while io1.read(1024, buffer)
   io2.write buffer
end
