How about this one, no $arg needed:
which checks from line #1 till /Listen/ is encountered the first time. The trick is "reusing" the "previous regular expression" for the range end definition. /Listen/ will be evaluated for line 1, and can be reused from then on.
How can I insert, say lines 500 - 700 from another file into the current file on the current line (cursor) that I am editing while in vi (AIX).
I know how to insert the entire file but how do you do it when you only need certain lines from a huge file?

prunehistory
PRUNEHISTORY(8) InterNetNews Documentation PRUNEHISTORY(8)NAME
prunehistory - Remove tokens from Usenet history file
SYNOPSIS
prunehistory [-p] [-f filename]
DESCRIPTION
prunehistory modifies a history(5)-format text file to "remove" a set of tokens from it. The tokens are removed by overwriting them with
spaces, so that the size and position of any following entries does not change. This has an effect similar to expiring the article, in
that it is still mentioned in the history database but cannot be retrieved.
prunehistory reads the standard input. The input is taken as a set of lines. Blank lines and lines starting with a number sign ("#") are
ignored. All other lines should consist of a message-ID followed by zero or more other fields (which are ignored). The message-ID is used
as the dbz(3) key to get an offset into the text file. Since innd only appends to the text file, prunehistory does not need to have any
interaction with it.
OPTIONS -p prunehistory will normally complain about lines that do not follow the correct format. If the -p flag is used, then the program will
silently print any invalid lines on its standard output. (Blank lines and comment lines are also passed through.)
This can be useful when prunehistory is used as a filter for other programs such as reap (a legacy program, probably no longer useful
with current versions of INN, but still available at <ftp://ftp.ruhr-uni-bochum.de/.subdisc1/local/jk.collection/>).
-f filename
The default name of the history file is pathdb/history; to specify a different name, use the -f flag.
