I'd probably do it with substr, usually, but you can do it using a regexp too. As the regexp does not match if you do not have enough chars, you do not have to worry about malformed strings (you only 'touch' strings that are meaningful).

This is a sample: 

use strict;
my $a;
my $from = 2;
my $len  = 2;

while( $a = <DATA> ) {
    chomp $a;
    print "Before: '$a' ";
    $a = $1 . $2 if $a =~ /^(.{$from}).{$len}(.*)$/i;
    print "After '$a'\n";
}

__DATA__
12345678
yellow
a
xx
