Switch it too a format and you wont need the otherwise clause, however it is
considered good form, mainly bacuase what would happen if you reran the code
with new data and you didnt have one of your year boundaries.  You the
programmer may never know that you had data going beyond 2007 or before
2002.  While one could say there shouldnt be any it always behooves one to
cover thier butt.

Proc Format ;
  Value Year ;
    '01SEP01'D - '28AUG02'D = '2002'
    '01SEP02'D - '28AUG03'D = '2003'
    '01SEP03'D - '28AUG04'D = '2004'
    '01SEP04'D - '28AUG05'D = '2005'
    '01SEP05'D - '28AUG06'D = '2006'
    '01SEP06'D - '28AUG07'D = '2007'
    Other                            = 'XXXX'
;
Run ;

Data Need ;
Set Have ;
  FY = Put( CNDTLET , Year. ) ;
Run ;


To me in some ways the format creates a more readable hunk of code.   And
readability is something I personally am always after.

Another solution would be to use the IntnX function to increment year to the
bound you want by using the shift operators and the period operators.  Then
simply use the Year function.

Data _Null_ ;
CnDtLet = '28Aug2002'd ;
FY = Year( IntnX( 'Year.9' , CnDtLet , 1 , 'B' ) ) ;
Put _All_ ;
Run ;


On the other hand your post does bring up something that people using the
select statement need to know before using it.  Good post and keep up the
good work Paul.

Subject: SELECT - Unsatisfied WHEN clause and no OTHERWISE clause
Date: Tue, 5 Sep 2006 09:24:25 -0400

Learned about using the Select statement in the "SAS Programmiing by
Example" by Ron Cody and Ray Pass...
http://support.sas.com/publishing/bbu/companion_site/home.html#s

So I tried it:
   SELECT;
    WHEN ('01SEP01'D LE CNDTLET LE '28AUG02'D) FY='2002';
    WHEN ('01SEP02'D LE CNDTLET LE '28AUG03'D) FY='2003';
    WHEN ('01SEP03'D LE CNDTLET LE '28AUG04'D) FY='2004';
    WHEN ('01SEP04'D LE CNDTLET LE '28AUG05'D) FY='2005';
    WHEN ('01SEP05'D LE CNDTLET LE '28AUG06'D) FY='2006';
    WHEN ('01SEP06'D LE CNDTLET LE '28AUG07'D) FY='2007';
    END;

Error message in log:
ERROR: Unsatisfied WHEN clause and no OTHERWISE clause.

This puzzled me. Unsatisfied When clause? Also, for this program, I saw no
apparent need for an Otherwise clause and left it out. I then tried adding
an otherwise clause, stuck in a proc sort, then run. Did not work.

It took a little digging but I found a good solution at:

Turns out that Otherwise clause has to be included and needs to be followed
by end. Thought I'd share this with others who are also in the begginning
stages of their SAS learning.
