I've been looking for a way to resort&rearrange hundreds of lines from a file, and then save the result in three of more files.
Im new to perl and i havent managed to produce a bigger script like this with guides.
The conversion goes like this;

First i get the raw list which formatting i cannot change directly:
- The first number is the category of the user - these could be sorted to multiple files, 1's in 1.txt and 2's in 2.txt and so on ) 
1 Förenäme1 Surname1 passwd1
1 Forename2 Surnäme2 passwd2
2 Forenäme3 Surname3 passwd3
3 Forename4 Surname4 passwd4

[download]
These are meant to be converted to a list like this:
- The first |-delimited field is in lovercase and ä,å->a, ö->o
- Other copied values are like in the unprocessed file
- Text-contents of FOO BAR and BAZ can be configured in the start of the process 
forename1 surname1|passwd1|Förenäme1 Surname1|FOO|BAR|BAZ|FOO Förenäme
+1 Surname1

Hope somebody could give me a push to the right direction. Thanks in advance.

Update:
Thank's Fizbin for your diligence! Works like a charm.
