Can't figure out how to find specific characters in specific columns
I am trying to find a specific set of characters in a long file. I only want to find the characters in column 265 for 4 bytes.
Is there a search for that? I tried cut but couldn't get it to work.
Ex. I want to find '9999' in column 265 for 4 bytes. If it is in there, I want it to print out the whole line.
Thanks for any advice.

NAME
PPIx::EditorTools::FindVariableDeclaration - inds where a variable was declared using PPI
SYNOPSIS
# finds declaration of variable at cursor
my $declaration = PPIx::EditorTools::FindVariableDeclaration->new->find(
code =>
"package TestPackage;
use strict;
BEGIN {
$^W = 1;
}
my $x=1;
$x++;"
line => 5,

DESCRIPTION
Finds the location of a variable declaration.
METHODS
new()
Constructor. Generally shouldn't be called with any arguments.
find( ppi => PPI::Document $ppi, line => $line, column => $column ) =item find( code => Str $code, line => $line, column => $column )
Accepts either a "PPI::Document" to process or a string containing the code (which will be converted into a "PPI::Document") to

("PPI::Statement::Variable") available via the "element" accessor.
Croaks with a "no token" exception if no token is found at the location. Croaks with a "no declaration" exception if unable to find
the declaration.
