Hello Dave,
"That's exactly how I always do it and it never seems to be a problem. What are those reasons it's undesirable?"
A mistake in an Internet address could send the reader to someplace he or she did not want to be, while if simple text is misspelt, it is merely mildly amusing. A misspelled Internet address could have actual consequences, and some Browsers look out for dangerous sites. And just finding the Internet address requires a little extra effort, and opportunity for making a mistake. I was looking for a way to link back to my Post using just the Post number. If there is no way to do this without getting the Internet address, then that is fine.
There have been several interesting responses here, and I appreciate them and will study and learn to understand all of them. I am elderly, so some things that are easy for most people require some study from me. These messages have already taught me that "Page number" is not reliable or uniquely defined in these messages. Live and learn. I have some more learning to do.
Thank you for your attention and the prompt response you already gave. Happy Easter.
ZM
