did I get it right?? as I understand it, the "closure" replaces a loop?
Assuming the function book loops through the books?
for the example I assume we have a pile of cards for each book...
function bestSellingBooks threshold
put the number of cards of stack books into numberOfBooks
put empty into theResult
for i = 1 to numberOfBooks
put field theSales of card i into @iSales
put booklistFilter (threshold, @sales) after theResult
end loop
return theResult
end function
function bookListFilter threshold, sales
if sales > threshold then return sales &"," else return empty
end function
if that is right, yeak closure is more compact & elegant!
but did I miss something? brainfade!
