Using the flip-flop operator:

#!/usr/bin/perl -w

use strict;

my @darray;
my $set;
my $eo;

while ( <DATA> ) {
    chomp();

    $eo = ( />DATA SET/ .. />DATA SET/ );
    /DATA SET (\d+)/;

    if ( $1 ) {
        $set = $1;
    }

    if ( $eo =~ /E0/ ) {
        $darray[$set] .= $_."\n";
        next;
    }
    
    $darray[$set] .= $_."\n" if ( $set );
}

for ( my $c = 0 ; $c <= $#darray ; $c++ ) {
    print "array element: $c\n";
    print "$darray[$c]\n";
}
