To cut a rectangular are out of any text file, first mark the top-left corner, then cursor down to the bottom-right. Everything in between will reverse-video, including the stuff outside your rectangle that you don't want, but don't worry. Now use the DM command "XD -R", which will cut the rectangular section from the text, and hold it in the paste buffer. The inverse operation--pasting a column into the middle of a table--is done with the companion command "XP -R" (don't use the PASTE key!); bear in mind that if things don't line up exactly, you will have some reformatting to do. I use the rectangular-cut command often when coding: to delete the first four spaces from 20 lines in a row, say, as when removing a FOR loop or other level of code. I use it so much, in fact, that I have bound the sequence to CNTL-W (for cut-window) with the DM command "KD ^W XD -R KE", in order to have it easily accessible. The corresponding copy command is "XC -R", but I have never used it. Also note that by appending "-F pathname" to these DM commands, the resulting cut/copy/paste can be written/written/read to/to/from the pathname specified. Please also note that the "rectangle switch" need not be present to make use of this pathname redirection switch. Indeed, it is in precisely this manner that "-F pathname" finds its greatest utility for me--and a few more bindings: cut to a file: "KD ^D XD -F &'Cut and copy to Pathname: ' KE" copy to a file: "KD ^C XC -F &'Copy to Pathname: ' KE" paste from a file: "KD ^I XP -F &'Insert from Pathname: ' KE" I find the prompts useful for remebering what I bound to what, and in case of typing error. Play with these until you are comfortable with them. Enjoy, Ross -------

The hardest one was getting ^K to kill to the end of the line correctly, making sure it joined the lines if you were already at the end of the line. I don't append successive kills to the kill-buffer, however. Barring this, the basic control, ESC and ^X key sequences work pretty much as in Emacs. > To cut a rectangular are out of any text file, first mark the top-left > corner, then cursor down to the bottom-right.

You can use ECHO -R to highlight the rectangle correctly. -- Ashwin. ARPA: Ram-Ashwin@cs.yale.edu UUCP: {decvax,ucbvax,harvard,cmcl2,...}!yale!Ram-Ashwin BITNET: Ram@yalecs

Here's something useful to know about the DM's rectangular feature: If
you set a mark (DR) and turn on rectangular echoing (ECHO -R), then
commands that take a marked region (e.g. XC) are made to operate on a
rectangular region, even if you don't give them (or they don't even take)
a -R switch. I define L1S (SHIFT-MARK) to be "DR;ECHO -R". Thus, if
I want to do a non-rectangular cut, I do "L1 (MARK), move cursor, L1AS
(CUT)" and if I want to do a rectangular cut I do "L1S (SHIFT-MARK),
move cursor, L1AS (CUT)". I.e. I don't need two CUT key bindings (one
with -R and one without) and two COPY key bindings (similarly). Also
the S (substitute) command obeys rectangularity established by "DR;ECHO
-R", even though S itself doesn't take a -R switch.
Hey, maybe it's not a *silk* purse from a sow's ear, but what about nylon?

These include incremental search, a backspace that deletes over word boundries and virtually everything else you would expect. I can package them up and mail them to anyone who wants if you can't wait for SR10.
