in thread display problem

Dear Moritz,

Thanks a lot for your help

But this is what I get from the display 

;04:20ELLO

[download]

Instead of 

song HELLO;04:20

[download]

But it works when I do 

chop($song);

[download]

Could you tell me why ? Thanks a lot

    Maybe your line endings are not the same as $/?

    The line endings on linux (LF), windows (CR LF) and Mac OS (CR? not sure...) are different, so if the input file has different line endings than your system, you have to set $/ to that value manually.

    chop just removes the last character, independently of what it is.

    The most generic solution might be $song =~ s/\s+$//, which removes all trailing whitespaces, and all line endings are considered to be whitespaces.

    See perlvar for the meaning of $/.
