st: Find the fiscal year for each obs

Dear Statalist,
I have two files. File A contains the daily stock price for each firm,
and file B contains the beginning and ending dates for a fiscal year
for each firm. See below for an illustration (data are hypothetical):
File A:
Firm Date Price
IBM 2009/01/15 xxxx
IBM 2009/01/16 xxxx
...................
3M 2010/07/01 yyyy
3M 2010/07/02 yyyy
...................
File B:
Firm Fiscal Year Beg. Date End. Date
IBM 2009 2009/03/01 2010/02/28
IBM 2010 2010/03/01 2011/02/28
..................
3M 2010 2010/06/01 2011/05/31
3M 2011 2011/06/01 2012/05/31
..................
Now, I want indicate in File A for each observation the fiscal year
the observation belongs to, according to the definition in File B.
Conceptually it seems easy: Just compare the date of the observation
in File A with the beginning and ending dates in File B. However, I
find it difficult to write code. Can you help me?
Thank you very much,
Yu Chen
