How do I search and replace ^j for ^m^J across the entire file?

You mean change \r\n to \n? I can't figure out if you want that or
the other way around.
Assuming RSTS, where entering CR gives you \r\n and entering LF gives
you just \n:
FN<cr><esc><lf><esc>EX<esc><esc>

It's FN<search>$<replacement>$ So lf to crlf is the reverse of what I
wrote.

Right.

Well, the real difference with FS and FN is related to the way teco
loads files into memory in "pages". Take for example the following
(assuming myfile.txt has many lines in it):
.teco
*ewmyfile.txt$$ - open myfile.txt for updating (Edit Write)
*ht$$ - print it all out
* - OK, where did it go????
The answer is that the editing buffer hasn't been loaded with any of
myfile.txt
*10000<a>$$ - OK, so my DECsystem-10 has lots of memory. Use the A
command to
- to load "pages" of myfile.txt into the buffer. As I'm lazy,
- do 10000 A's in a loop - no file I ever edited was bigger than
this!
- Now HT will do it's thing properly
Now getting back to FS and FN. FS does a "find and replace" in the
current buffer. FN does this,
writes the current buffer out, and "yanks" in the next page. The teco
command to do the yank is Y.
So for small files, FS and FN do the same, but for large files the
results may well differ - something
I learnt a long time ago....

OOPS. Brain lockup.
FN means "replace next anywhere between here and end of file" while FS
means "replace next in current buffer". Current buffer holds whatever
fits, or up to the next form feed character.
To do replace-all, you need a loop:
<FN<lf>$<cr>$;>
Angle brackets are loop delimiters; semicolon is "exit loop if
preceding command failed".

The flashbacks are happening again...They warned me these could happened for

You're giving me headaches! :-) Recollecting things loooong
forgotten... Never used teco, but nspeed, Data General's clone
or copy of it. Same difference.
I have a little RDOS pocket command ref, I think I'll go look
at the nspeed commands, maybe generate a migraine or religious
experience. (Probably just indigestion).
