in thread parsing question

This sets the default line-separator (held in "$/", normally set to "\n") to undef, so that whatever comes in from STDIN (<>) will get slurped up, split on the string "-{103}", and assigned to @sections.

A short example... put the following into a script named "":

#!/usr/bin/perl -w use strict; my @sections = split 'FOO', do {local $/; <>}; close *ARGV; print join("\n", @sections);

Then, put the following into a file called "test.txt":

FOObarFOObarFOObarFOObarFOObar FOObarFOObarFOObarFOObarFOObar FOObarFOObarFOObarFOObarFOObar

Then, run the following at the command-line:

cat test.txt | ./

    Thanks for the reply. I'm not seeing where "-{103}" is, in the text file I'm parsing.

    UPDATED: Nevermind the above. :-) I'm such a newbie. I didn't recognize the {} as being quantifiers in a regex. So, "-{103}" is simply the line of hyphens used to separate the sections in the text file.
