Dear Elan, thanks a lot for your answer. I applied your suggestion. It works only partially. Indeed, I am sorry but I forgot to mention in my initial mail that about a quarter of my identifiers are not made of six figures (eg. "111112") but of five figures and a letter (eg "11111U"). For the later case, the procedure does not apply. If I read your procedure well, at the end I should only have three variables : date, firmid and Vol that contains my variable of interest. However, here, I keep the columns for all the cases with a letter in their name. If anyone has an idea, it would be great.
