That's not a CR (CR is 0d), it's an LF, i.e. newline. The variable you want to customize is require-final-newline. But why would you want to remove it? Text files should be a sequence of lines, and each line should end with a newline. Some programs don't process the last line correctly if it doesn't end with a newline. -- Barry Margolin, barmar@alum.mit.edu Arlington, MA *** PLEASE post questions in newsgroups, not directly to me ***
