I have discovered some of this. In particular I found
pop/help/vedkeys.pdf which has similar info (I haven't verified that is
identical to 'pop/help/linuxterm'). It seems that $TERM=xterm and
$TERM=linux both work; at least the error message goes away.

Here's a brief transcript:
$ TERM=linux xved $usepop/pop/teach/teach
;;; WARNING - PIXMAP FILE NOT FOUND
;;; INVOLVING: '$usepop/pop/x/ved/bitmaps/ved_48.xbm'
;;; PRINT DOING
;;; DOING : runproc
;;; editing: /home/bill/Poplog/poplog/V16/poplog_base/pop/teach/teach,
ON LINE 1
and a second window pops up with the title
Ved - /home/bill/Poplog/poplog/V16/poplog_base/pop/teach/teach
The first line of the text area says "TEACH TEACH Last revised,
A.Sloman, Sept. 1987"
which seems to be right.
BTW I believe I am using the version 16 software, and the header that
appears when invoking pop11 from the shell prompt says 16.0.
Now from pop11:
$ TERM=linux pop11

TEACH TEACH Last revised, A.Sloman. Sept 1987
-- HOW TO READ POPLOG TEACH FILES ------------------------------------
etc. So it appears the file is in the right place and I can coerce ved
into editing it. But consider this:
$ TERM=linux pop11

I should be clear: I am using Control-G (^G) for ENTER since I found
that key binding in $usepop/poplog_base/pop/help/vedkeys. It seems to
work -- it kicks the cursor to the left end of the command area and
"erases" whatever was there. And yes, the file
$usepop/poplog_base/pop/help/linuxterm says that the <ENTER> key at the
far right end of the keyboard is bound to ENTER, and it seems to work
that way.
That's all I know. Thanks for your help,
Bill Wood
