Brian, Ronald, et al: I don't think this particular problem is a good one for scripting. The reasons for saying that are: 1. In writing some scripting, I found that the data supplied by Yahoo is very "dirty". By that I mean that there are a number of tickers that they list on the industry, etc. pages that are either out of date or just plain wrong. I had to develop a routine to gather all of the tickers and then submit them to another part of Yahoo just to see if they were valid. In doing so I would get messages that some of them had been changed to something else or they didn't exist. I ran it last nite and got a new oddball situation: for one ticker it said that it had been changed but the new ticker it gave was the exact same as the old one and I hadn't programmed for that so I got into an infinite loop in that routine. Its been fixed now but you see the problem. 2. You'll also get a lot of chaff - tickers for the pink sheets, etc. Some people may want them others not - so you've got to provide a way for them to cherry pick the ones they want. Doing a GUI in script will add a higher level of complexity to the project. 3. After all of the tickers have been verified you can still have tickers that Yahoo says are "OK" but when you do to download the quotes they may not have any. So, you've got to figure out which one's they are. AQ doesn't tell you - you have to look at all of the files that are downloaded and detect the missing ones. 4. Then there's the ongoing maintenance problems - new tickers, deleted tickers, changed tickers, etc. All, in all - for a scripting project (beginning or otherwise) this one is very complicated and I think you should learn to crawl first. d

I have no scripting experience at all, but next week, I am starting a home study of scripting. The links below came up instantly on a google search, so I am sure that I will have no problem finding enough study material. If this yahoo data project involves a huge amount of repetitive typing of symbols, then I would like to join in on developing the thousands of sub routines that are probably, required. I learn best when I am working on a project that will benefit me. I am willing to devote a substantial time to this project. I know that the time of experienced scripters is valuable, so would ask a question only when I can't find the answer in a google search. Maybe there are others wanting to learn at least a little about scripting, and would be willing to dovote a substantial amount of time to helping.
