($endstore[$ctrend][0], $endstore[$ctrend][1],
 $endstore[$ctrend][2], $endstore[$ctrend][3],
 $endstore[$ctrend][4]) = @arr;

[download]

can be abbrieviated to 

@{$endstore[$ctrend]}[0..3] = @arr[0..3];

[download]

If I read the intent correctly, it can be abbrieviated further to 

$endstore[$ctrend] = [ @arr ];

[download]

Of course, since $ctrend is always being incremented, we simply want 

push @endstore, [ @arr ];

[download]

Final result: 

while (my @arr = $sth2->fetchrow_array() ) {
    push @endstore, [ @arr ];

    my ($field1, $field2, $field3, $field4, $field5) = @arr;
    $endflag=2;
    print STDOUT "Field 1: $field1  Field 2: $field2  "
    .            "Field 3: $field3  Field 4: $field4  "
    .            "Field 5: $field5\n";
}

Note that [ @arr ] can't be replaced by \@arr since you'd be pushing multiple references to the same array.
