Yes, you can edit multiple files in the same session. You just need to put them in different buffers. But you can't show multiple files on the screen at the same time.

*incl sys$login:toc.com =toc

e.g. 

You can switch between buffers, even going back to the same line you were on! Or you can specify the line number.

(EDT probably had this from its earliest days -- perhaps even day 1. No need to be "snitty" about it. But I'm not an EDT historian. I started using it c. 1985 and I'm pretty sure it had it then.)

$ ed login.com
    1       $! Template login.com procedure for DECUServe users.
*incl toc.com =toc
*incl sys$login:tob.com =tob
*show buff
=TOB    1529    lines
 TOC    1546    lines
 MAIN   1*      lines
 PASTE  No      lines

*=main.

will take you back to buffer "main" and put the cursor on the line it was when you switched to a different buffer. (That's what the period does.) You can even define a key combo that does this. GOLD M is typical. 

You can even edit the PASTE buffer!!! Yes, that's right. Not only can you cut and paste with EDT; you can actually edit its "clipboard", the PASTE buffer, as, being a buffer, is just another buffer!

To write a buffer to disk, go to that buffer with 

=<buffer name> 

and use the WRITE command:

*write temp.tmp

Wait, there's yet more! EDT can recognize . . . <drum roll, please . . . final loud drum note> . . . lowercase letters!!! What a surprise, eh?

There's even more. Check the manual.
