[DUG]: Friday Challange

Hi all,

Further to my enpty string question, I'm writing a lot of

functions that return a set of strings joined by a separator

ie 'col1, col2,...' or 'col1 = 'a' and colb = 'b'' (as you may guess

these are all parts of SQL Statements)

given a function 'Itemcount' that returns the number of items

and item(i) that returns the item string, and function sep what is the

best form of such a function

to seed the duscussion I'll give you one of my variants

function statement: string;

var

I: integer;

begin

Result := '';

for I := 0 to pred(ItemCount) do

if I = 0 then Result := Item(I)

else Result := format('%s%s%s',[Result,Sep,Item(I)])

end;

Variants and explainations pls

Neven
