Thank you very much, it works!
I'll explain you why I want to use tuples.
I have a range of products 1:N. Every product can be made of several
mutually exclusive bases. I need to make a lot of loop of this kind
for k in Products, b in Bases
if accordance[k,b]=true
...
end; end
I want to create an array of tulpes, so that I could decrease my loops to
for k in Products, b in Bases[k]
where Bases[1] is the tuple of bases for product[1]
I could use an array, but one product can correspond to different number of
bases.
That's why I decided to use tuples.
Thanks again!
