Unwanted line breaks-- why?

[jeffrgsf]

Dearest Monks,

I am new to programming and this site is helping me A LOT. I'm so close to finishing this script to chop up strings of classical music work titles into title, key, instruments, etc. but for some mysterious reason perl adds a line break I don't want. Why why why??

Script reads a big text file and generates a new file-- ideally with one-to-one line correspondence. These extra line breaks are RUINING MY LIFE! (Ok, not really, but they're a bummer.)

Examples of what I mean and the code I wrote are below.

Sorry this is such a noob question. Thanks for any help!!!

Example input lines:
----------------
Concertino, For Clarinet & Strings (Or Piano) (Based On Tartini Sonata Themes)
Concertino, For Clarinet, Piano, Violin & Cello, Op. 73
Concertino, For Clarinet, Violin & Piano, "Fritz Zorn"
Concertino, For Contrabass & Orchestra
Concertino, For Corno, Bassoon & Orchestra In E Flat


Example output lines (not what I want-- should be each on one line!)
----------------
Concertino, For Clarinet & Strings (Or Piano) (Based On Tartini Sonata Themes) -;;- Concertino Based On Tartini Sonata Themes
-;;- -;;- Clarinet & Strings -;;- -;;- -;;- Or Piano -;;-
Concertino, For Clarinet, Piano, Violin & Cello, Op. 73 -;;- Concertino Piano Violin & Cello
-;;- -;;- Clarinet -;;- Op. 73 -;;- -;;- -;;-
Concertino, For Clarinet, Violin & Piano, "Fritz Zorn" -;;- Concertino Violin & Piano
-;;- -;;- Clarinet -;;- -;;- "Fritz Zorn" -;;- -;;-
Concertino, For Contrabass & Orchestra -;;- Concertino -;;- -;;- Contrabass & Orchestra
-;;- -;;- -;;- -;;-
Concertino, For Corno, Bassoon & Orchestra In E Flat -;;- Concertino Bassoon & Orchestra -;;- E Flat
-;;- Corno -;;- -;;- -;;- -;;-


Eventually I need to run this on a file over 170,000 lines, but I'm just doing short bits until I get the bugs worked out. I know it would be better not to be posting all this code, but I can't figure out where the problem is.
