So you can just start and end each line with a quote, and leave off the backslash. Similarly, if you need a newline at the end of each line, you can use the \n just before the trailing quote. Naturally I agree with you that this case is better handled in Python with triple-quote. I never use the backslash at end-of-line to continue a statement to the next. Not only is it a readability problem, but if your editor doesn't have visible spaces, you can accidentally have whitespace after the backslash, and wonder what went wrong. -- DaveA
