I'm not sure what that sentence means, and I've written code that uses co_lnotab. I think they are trying to explain the difficulties with abandoned approaches. Don't worry about that. Look at the code in the comment there to see how to interpret the bytes in co_lnotab. Here's the code in coverage.py that reads it: https://bitbucket.org/ned/coveragepy/src/a69ae93817be94e400df257e1b1e41cf37c9b146/coverage/parser.py?at=default#cl-377 if that helps. Just out of curiosity, what are you writing, it sounds interesting! :) --Ned. > > Regards > > -- Ned Batchelder, http://nedbatchelder.com -- https://mail.python.org/mailman/listinfo/python-list
