Thanks Alan for clearing that up...I was trying to see why my "\r\n"
does not print 2 empty lines when I stumbled across this 'gotcha'.

\r is a carriage return which literally means that the printhead
carriage should return to the start of the line. You need a line feed
character if you want a new line too.
Unfortunately some OS use \r to do both, others need both.
The safe way is to use \n (new line) instead.

So being pedantic XP is correct, IDLE is wrong but in fact because the
conventions are so mixed up right and wrong is a bit woolly.
Which response were you trying to get?
