Dear All I think "yahoo download" package is very nice and useful but  at the moment I use this function in a very inefficient way. E.G. ----------------------- loop foreach i A2A.MI ANIM.MI ATL.MI [cut]     A=yahoo_full("$i") endloop -------------------- If i want to download a long list of stocks should be better to use a list, instead typing each ticker. But when i read the 14th Chapter (named list) - which is very clear also for a newbe in programming - I get confused because mostly speaks about variables lists. And I was unable to extract some useful hint from the 14.2 paragraph, which seems the right place to look for. So again I ask your help. By the way I found curious i was unable to donwload with that function no less than 2 days. I mean, if I try to donwload only one day i can't. Many thanks Guido
