Is it possible to make do something like this in udf. make a cell loop in another cell loop. Thanks for your response begin_c_loop(c,t) { do something here begin_c_loop(c,t) {

} end_c_loop(c,t) } end_c_loop(c,t) P

Yes it's theoretically possibile but I don't undestand what physically means. Anyway the answer is yes but You don't have to use the same t pointer for the 2 loops...Luca

Excuse me I meant "you don't have to use the same cell counter c". Luca
