Hi gbwien,

what you want is not very clear to me and there are some unanswered questions. Just like Eily, I don't think you need a hash at all.

Assuming the last data line in your post is your desired output, you could try something like this: 

use strict;
use warnings;

my $msisdn;
while (<DATA>) {
    $msisdn = $1 if /^\s*MSISDN=(\d+);/;
    if (/\s*CF=([\w-]+);/) {
        print "$msisdn,$1\n";
    }
}

__DATA__
<BEGINFILE>
<SUBBEGIN    
    IMSI=23341400010332;
    MSISDN=411206901000;
    CF=CFU-ALL-PROV-NONE-YES-NO-NONE-YES-65535-NO-NO-NO-NO-NO-NO-NO-NO
+-NO-NO;
<SUBEND

which will duly print: 
411206901000,CFU-ALL-PROV-NONE-YES-NO-NONE-YES-65535-NO-NO-NO-NO-NO-NO
+-NO-NO-NO-NO
