Your code is a complete train wreck so I'm not going to even try and guess where your head is at. Instead, working from your specification, I guess you want something like:

use strict;
use warnings;

while (defined (my $header = <DATA>)) {
    my @parts = split ' ', $header, 17;
    
    next if @parts < 12;
    processEvent ();
    print join (' ', @parts[3, 4, 6, 5, 7, 8, 11]), "\n";
}


sub processEvent {
    <DATA>;

    for (1 .. 8) {
        my $line = <DATA>;
        
        last if ! defined $line;
        
        my @parts = split ' ', $line;
        
        splice @parts, 3, (@parts - 3) if @parts > 3;
        s/[^\d\s.]+/ /g for @parts[1 .. $#parts];
        s/^\s+|\s+$//g for @parts;
        print join (' ', @parts), "\n";
    }
}

Note that this code is not at all robust and depends on the event records' layout being consistent.

True laziness is hard work
