There are no stupid questions, only questions that are so broad they cannot
be easily answered. Oh, and stupid answers, there are definitely those too.
First, what is a "text delimited file." I think what you mean is
"delimited text file." This is just a text file, like one you might create
with notepad in Windows. The delimited part refers to something between
pieces of text that separates them. Lines are often separated by a
carriage return.
You can also delimit "fields" within a line of a text file. Here's an
example of that:
Perl^Larry Wall^www.perl.com
Python^Guido Van Rossum^www.python.org
Ruby^Yukihiro Matsumoto^www.rubycentral.com
Each line can be thought of as a record and each of the sections of each
record separated by the caret ("^") sign can be considered a field. This
translates roughly into columns and rows in database parlance.
Let's say this bit of text is in a file called cool_langs.txt. Here's how
you might do something with it in a perl program.
#!/usr/bin/perl
use warnings;
use strict;
open( LANG, "cool_langs.txt" ) or die( "File open error: $!\n" );
while( <LANG> ){
chomp;
my ( $lang_name, $author, $url ) = split /\^/;
print "Language: $lang_name\n";
print "Author: $author\n";
print "More Info: $url\n\n";
}
close( LANG);
Well, that's it. Look at Learning Perl, 3rd edition for this type of stuff
and more.

Troy
