Problem of vocabulary : retrieve element of a list of a list
Hi,
I read the posts for 2 hours and ?list and tried many comninations but I
haven't found the answer to this basic question. So I decided to post my
question even if it is a silly one ...
What is the instruction to retrieve, for example, the "D" of the first list
?
Thanks in advance,
Ptit Bleu.
