Seriously ? you're learning ED in the 21st century ?
Now, maybe ED is way more powerful than EDLIN, the ED-inspired editor of MS-DOS 3 which i have been forced to use in early days ... I can tell you it *really* made me regret the C64's BASIC edition mode (list 1-n giving you n first lines, and re-typing over existing lines replaced them).
The point of learning ed is to become better in using (g)vi(m). When you know the history (ed>ex>vi) of the command you use, the commands will make more sense.
(yes i know i'm replying to a 4 year old post...)
What's wrong with replying to 4 year old posts?
Well, may be he thought the post was outdated.
By the way, right now, I am learning ed. And, I find great joy in practicing the editor.
I am here actually because of Google. I searched how to activate ed command history (if any of course).
And so far, I get none.
Well, even if there is no command history, at least I have verbose error message (H) and a prompt (P).

I love to read science books. They make my day and I get ideas for awesome blog posts, such as Busy Beaver, On Functors, Recursive Regular Expressions and many others.
Take a look at my Amazon wish list, if you're curious about what I have planned reading next, and want to surprise me. :)
