Personally, I'd use the foreach code from the original question. I find it clearer and cleaner than even the "wish" code. For one thing, "@fields" doesn't have to be repeated in that code. If grinder finds `$totals{$_} += $delta{$_} foreach( @fields );` "ugly", then I doubt `use mapcar; mapcar { $_[0] += $_[1] } [@totals{@fields}], [@delta{@fields}];` [download] would fair any better. - tye (but my friends call me "Tye")	[reply] [d/l] [select]

    use mapcar;
    mapcar { $_[0] += $_[1] } [@totals{@fields}], [@delta{@fields}];
