How can i merge these two files into several...
Given are File A and File B
File A has for example 5 lines:
AAA
BBB
CCC
DDD
EEE
File B has 3 lines:
111
222
333
How can i merge A and B into:
111
222
333
AAA (first line from A)
then a new file:
111
222
333
BBB
etc.
so that in the end i have 5 new files, where the first three lines are from File B, and the last, 4th line, is always "the next" from File A, and also, how can these files be named automatically, like File1, File2, File3...
Thank you very much in advance, every help is much appreciated!

file::inplace
File::Inplace(3pm) User Contributed Perl Documentation File::Inplace(3pm)
NAME
File::Inplace - Perl module for in-place editing of files
SYNOPSIS
use File::Inplace;
my $editor = new File::Inplace(file => "file.txt");
while (my ($line) = $editor->next_line) {
$editor->replace_line(reverse $line);
}
$editor->commit;
DESCRIPTION
File::Inplace is a perl module intended to ease the common task of editing a file in-place. Inspired by variations of perl's -i option,
this module is intended for somewhat more structured and reusable editing than command line perl typically allows. File::Inplace endeavors
to guarantee file integrity; that is, either all of the changes made will be saved to the file, or none will. It also offers functionality
such as backup creation, automatic field splitting per-line, automatic chomping/unchomping, and aborting edits partially through without
affecting the original file.
CONSTRUCTOR
File::Inplace offers one constructor that accepts a number of parameters, one of which is required.
File::Inplace->new(file => "filename", ...)
file
The one required parameter. This is the name of the file to edit.
suffix
The suffix for backup files. If not specified, no backups are made.
chomp
If set to zero, then automatic chomping will not be performed. Newlines (actually, the contents of $/) will remain in strings
returned from "next_line". Additionally, the contents of $/ will not be appended when replacing lines.
regex
If specified, then each line will be split by this parameter when using "next_line_split" method. If unspecified, then this
defaults to s+.
separator
The default character used to join each line when replace_line is invoked with a list instead of a single value. Defaults to a
single space.
INSTANCE METHODS
$editor->next_line ()
In scalar context, it returns the next line of the input file, or undef if there is no line. In an array context, it returns a single
value of the line, or an empty list if there is no line.
$editor->replace_line (value)
Replaces the current line in the output file with the specified value. If passed a list, then each valie is joined by the "separator"
specified at construction time.
$editor->next_line_split ()
Line "next_line", except splits based on the "regex" specified in the constructor.
$editor->has_lines ()
Returns true if the file contains any further lines.
$editor->all_lines ()
Returns an array of all lines in the file being edited.
$editor->replace_all_lines (@lines)
Replaces all remaining lines in the file with the specified @lines.
$editor->commit ()
Completes the edit operation and saves the changes to the edited file.
$editor->rollback ()
Aborts the edit process.
$editor->commit_to_backup ()
Saves edits to the backup file instead of the original file.
