Function: under Data - Get External Data - New Web Query

good day friends,

i would like to query the stock quote copy to the data to the spread
sheet
by using the function "New Web Query" and link to the web page:
http://finance.yahoo.com/q?s=msft
msft = stock code,

my question is: how can i make the stock code be a variable, or is it
possible to prepare a stock code list to retrieve the data to spread
sheet?

thanks for your help
