Hello,
I was wondering about <control> L. Precisely what is the correct
way to use this. The reason I'm asking is because when I enter
a "^L" in the first column of an article it doesn't seem to work
when I see the article I just posted. I enter the "carrot" sign
over the 6 on my keyboard, followed by an L. Is this correct?
Will this work after the article is off site?
Thanks...

You need a actual ^L, which is ASCII character 12, and I think it needs to be the first character on the line. If you are using emacs, type a ^Q and then the ^L. In vi you can just type ^L without any "prep" characters.

Is this correct? A very simple mistake. You are entering two characters, "^" and "L", when you want to enter one character, "^L", which unfortunately has the same print representation. (You will often see control characters denoted less ambiguously: CTRL/L, Control-L, C-L, <CTL/L>, etc.) Control-L should do what you want - it is also known as Form-Feed, and most software responds to it as though it denotes a page break. First, find the key on your keyboard marked CONTROL, CTRL, CNTL, CTL, or something of that sort. (The marking may be eccentric on machinery from eccentric hardware manufacturers - I hear that it is marked ALT on IBM PC keyboards, to confuse those of us who _know_ that ALTMODE is (or was until 1968) 033 (octal), now known as ESCAPE.) It should be on the left hand side above the SHIFT key and it is used similarly. A control character is typed by holding down CONTROL and pressing another key simultaneously. Note that some control characters are not typed in the obvious way on some terminals: for example, on VT100s, "^@" (Control-Atsign) is typed as though it were "^ " (Control-Space); "^_" (Control-Underbar) as "^?" (Control-Question); and "^^" (Control-Caret) as "^~" (Control-Tilde). Refer to the documentation for your terminal or terminal emulation software for the surprises your manufacturer has decided to give you. There are 32 (decimal) control characters corresponding to all upper case letters and to the characters: "@", "[", "\", "]", "^", and "_"; some people argue that DELETE (RUBOUT) is also a control character.

Inserting a Control-L into a news message is not a good thing to do. Some terminals and/or news readers do not pause when they see ^L In some cases - it might clear the screen or do something equally offensive. Instead - just insert a few blank lines if you want to delay the punchline to a joke. Some news readers will pause before they see the character sequence preceeding a signature: <return>-- <return> You might want to use that instead. To change rn to do this, you can set the environment variable RNINIT to have the following string: -EPAGESTOP=^--\ or -EPAGESTOP=^-- which will cause a pause on the lines separating digest articles as well as signatures. I think that will work. -- Bruce G. Barnett <barnett@crdgw1.ge.com> a.k.a. <barnett@[192.35.44.4]> uunet!crdgw1.ge.com!barnett barnett@crdgw1.UUCP

Try telling that to the folks in rec.arts.movies. The lack of insertion of Control-L has been the cause of major flamage over there.

Or Citizen Kane. >Some terminals and/or news readers do not pause when they see ^L >In some cases - it might clear the screen or do something equally offensive. You take the risk -- mess up a few people's screens, or get tons of hate mail and flamed all over the newsgroup for revealing the suprise ending to "Bill and Ted's Excellent Adventure." >Instead - just insert a few blank lines if you want to delay the >punchline to a joke. But that won't really protect people from movie spoilers. >Some news readers will pause before they see the character sequence >preceeding a signature: ><return>-- <return> But not all will. And you'll make the people who don't have that feature *really, really* mad at you. If you choose to post spoilers without ^L, that's your prerogative.

Perhaps you are thinking of IBM 3101 terminals? Note: Some PC keyboards put CAPS LOCK where CTRL should be, and CTRL on either side of the space bar. The major PC manufacturer that didn't learn about CTRL until late in the game was not IBM, but Apple! (BTW, ALTMODE on old ASR 33s sent 175 octal.) -=EPS=-

You should mark the subject line with *SPOILER* If you do, and don't put in a Control-L, then no-one should flame you. If they do, you can flame them back. I guess you could also insert 25 (or more) linefeeds. But even that's not portable, as some people have 40+ lines on their workstation. -- Bruce G.

Actually, I'm not sure - I try to keep my hands off them. :-) I've recently heard of this ALT key, a shift key of some kind, but I guess I'm not clear on what it is supposed to do. >The major PC manufacturer that didn't learn about CTRL until late >in the game was not IBM, but Apple! True enough - it's that funny little "cloverleaf" thingie to the left of the space bar, isn't it? And all the documentation depicts this cloverleaf thingie wherever there should be Carets or Uparrows. >(BTW, ALTMODE on old ASR 33s sent 175 octal.) Old Teletypes indeed used 175 for ALTMODE, 176 for ESCAPE, and 033 had yet another name. (?PREFIX? If I recall correctly.) Documentation from MIT for programs like DDT (Dynamic Debugging Tool), developed circa the ANSI X3.4-1968 revision of ASCII, generally refers to 033 as ALTMODE. (DDT has commands such as "$X" (ALTMODE X) for single-step and "$$X" (ALTMODE ALTMODE X) for stepover-routine.)

Inserting CTRL/L in files is the standard page break. If your terminal is getting screwed up something is wrong with your newsreader--it's supposed to be echoed as ^L, not literally. If your newsreader supports an alternate PAGER you may be able to fix it yourself, otherwise you'll have to ask your administrator. Putting 25 linefeeds in articles is not going to win you any friends, just an honorable mention in a KILL file. -=EPS=-

And all the documentation depicts this >cloverleaf thingie wherever there should be Carets or Uparrows. The new Macintosh keyboards have Control, Option and "cloverleaf"-- and they all perform different functions. Some terminal emulators used "cloverleaf" to simulate a control key, but this was never a "standard." -=EPS=-

My problem with ctrl-L is in the nn reader program.
It doesn't clear my screen, and just writes the next page over it, making
for a very cluttered look. My only solution right now is to pull down
the help menu and then exit, leaving a fresh screen on which the pager
can print the new stuff.
Very annoying, there should be a way to get around that. Oh well....
