I rean news on a SUN running Berkley 4.3 UNIX, with the newsreader 'rn'. I read groups by following subject threads with the ^N option (In fact, I load rn as 'rn -S' which automatically puts me in ^N mode). The problem is, sometimes the threads are LONG. What I'd like to do is to be able to determine in advance how long a thread is. With my limited (but slowly growing!!) knowledge of macros, I can't find a way to do this. Anyone have any ideas on how to construct such a macro? (I realize I could use '=' and count them myself, but this is an inelegant solution.) Thanks for any ideas.

Available by FTP from someplace [I forget where --- check news.software.nn for details], will run on your SUN, no sweat, and is very very nice.

Try /<esc>s/= at the reading level or /%s/= at the macro level. This should be
equivalent to the = command just for the subject of your interest.

Are you explicitly typing the "-S"? If you are, you might want to try placing it in an environment variable called RNINIT. >The problem is, sometimes the threads are LONG.

How about this macro: @= /%s/=\n Which creates a command '@=' which is like '=' but only for the subject of the current article. -- Chip Rosenthal | Yes, you're a happy man and you're chip@chinacat.Lonestar.ORG | a lucky man, but are you a smart Unicom Systems Development, 512-482-8260 | man? -David Bromberg

In article <862@chinacat.Lonestar.ORG> I make an ass of myself: >How about this macro: > @= /%s/=\n Arrgh!! That does very strange things if the subject contains a slash. The following will handle it: @= /%`echo "%s" | sed -e 's|/|\\\\/|g'`/=\n Obviously this is going to be much slower. You could compromise with something using %( ? : ) which would handle a single slash -- that wouldn't involve the shell escape. Just don't use it to search a thread with a subject something like "need TCP/IP for Apple ///". -- Chip Rosenthal | Yes, you're a happy man and you're chip@chinacat.Lonestar.ORG | a lucky man, but are you a smart Unicom Systems Development, 512-482-8260 | man? -David Bromberg
