Hello,
I have written a small script that parses an (ugly) HTML file line by
line and converts the relevant information to CSV. During parsing, I
heavily use string concatenation to glue together parts of text that
belong together (but might be separated in the original file by tags
or newlines). In the code, the expression
$oldstring = $oldstring.$newstring
occurs very often.
Frequently, the strings get longer than 256 characters. At this point,
the string concatenation refuses to add anything to $oldstring. How is
it possible to avoid that?
Thanks in advance for answers on a (maybe very newbish) question
Piet

Your post appeared twice. Please don't post multiple copies of the same
question.

You'll need to provide a short self-contained script that still exhibits
the problem to support such an outrageous claim.

#! perl

use strict;
use warnings;


my $str = 'a';

$str .= 'a' for (1 .. 999_999);

print length($str), "\n";

__END__

You've misdiagnosed your problem. Perl is very capable of dealing with
arbitrarily long strings. Therefore, the strings are being cut off by
something else. My guess would be a fixed length database field that
you might be storing them in. Since you didn't provide any code, we
have no way of pointing to you to what your actual problem is.
