It’s a line editor (meaning, you can’t see all the text at a time. You query line numbers and it spits it back, but it came before vi, where you can use
hjklto navigate up and down the screen).How was it used? I find it hard to believe that people memorized their code well enough that they could remember what was going on in line 5 when working on line 20?
Using a line-based editor isn’t that hard.
- For one, yes, real programmers (as we all were back then) do remember their lines.(*1)
- Next, when on a writing terminal, one lists the working on section once, so all you need to do to take a look is pull the paper.
- On a dump terminal one could just issue a list (print) command for the actual range, or
,pfor all, as often as needed.
