Hi Don,

I'm trying to capture an english sentence in a record.
This sentence could be very long and span multiple lines in a file.

My perfect record separator would be a period, exclamation point, question mark, semicolon or colon.

However, my code sees the word "Mr." it thinks that's the end of the sentence because of the period that is part of Mr. So I want it detect that "Mr." is NOT part of the record separator.

Semantically:
Not (Mr.) but ok with any of these [.!?;:]

But syntactically I don't know how to do this, I'm trying like this:
Code:
 RS = (^Mr. | [.!?;:])

But its not working?

extract_usage_from_stx()												  extract_usage_from_stx()

NAME
extract_usage_from_stx - extract "Usage:" messages from manpages written in Stx SYNOPSIS
extract_usage_from_stx [ file file ... ] DESCRIPTION
Process the given files, which should be manpages written in Stx, stripping away everything that is typically not included in a "Usage:" message. If no files are given, read standard input instead. A "Usage:" message is a message typically printed when a program is called with incorrect arguments or when help is specifically requested, for example with a --help command line option. A "Usage:" message is typically a subset of the information provided on a command's manual page. The information left in the "Usage:" message by extract_usage_from_stx includes: o the command synopsis, as given in the "SYNOPSIS" section o the command line options, as given in the "OPTIONS" section, together with the first sentence of their description. A sentence is taken to end at a period (.). The output of extract_usage_from_stx is still in Stx format, which you might want to further process to produce the actual "Usage:" mes- sage. OPTIONS
--version, -V Just show version information and exit. --help, -? Just show a short help message and exit. SEE ALSO

The end-condition of a sentence is too strong. AUTHOR
