I added TECPUR 508, and now EMACS 24 and 25 will start.

However, they want to open EMACS; .EMACS (INIT). There's probably some necessary TECO code there. Without it, no EMACS commands except ^X ^C seem to work.

[larsbrinkhoff]

The EMACS version is from [PURE], not the TS file.

[larsbrinkhoff]

We now have .EMACS (INIT). EMACS 24 and 25 start without complaint. There is no mode line.

Cursor movement using ^P ^B ^N ^P M-F M-B works. Some commands unexpectedly open the TECO minibuffer; they probably have different meaning from today.

Find File is Read File and is bound to ^X ^R. Write File is unchanged.

[larsbrinkhoff]

Some interesting commands:

• ^X ^C - same
• ^X ^R - Read File
• ^X ^W - Write File
• ^X B - Select Buffer
• ^X T - Exchange Characters (transpose, now ^T)
• ^C - Prefix Control-Meta
• ^^ - Prefix Control
• ^C ? - Help
• Control-? - Describe (From SUPDUP: Control-^ Control-^ ?)

[larsbrinkhoff]

There's no M-X for extended commands. Typing just ALTMODE will present a TECO minibuffer.

Clarification: EMACS 24 uses a single ALTMODE to enter the TECO minibuffer. EMACS 25 uses a single ALTMODE as a meta prefix, and a double for the minibuffer like all subsequent vertsions.

[larsbrinkhoff]

EMACS; TS 13 starts EMACS; [PURE] 24, and EMACS; TS 14 starts EMACS; [PURE] 25.

The current version in this repository is EMACS; [PURE] 162, started from EMACS; TS 126.

The EINIT library writes to EMACS; [PURE] >, and PURIFY writes to EMACS; TS >. So I suppose the former was done more often than the latter.

@atsampson, I found this in EMACS1; CCL 196:

!@ TECO:! !C Make XGP listing of macros file.
Example: 73 MM@ TECO^[USRCOM >^[20FG^[ (notice that
73 is the page height with the font 20FG).
20FG and 73 are actually the defaults, so that
MM@ TECO^[USRCOM^[^[ is equivalent.!

It seems it's easiest (necessary?) to first :CWD EMACS1, then run EMACS. M-X Load Library◊purify, then e.g. M-X @ TECO◊USRCOM.

?MACS ought to be a slightly older version than EMACS 24, see #1052.
