Help on INI file

Hi all,
I'm building a DTS package that needs to take parameters from an INI
file. The SQL statement in the Transform task goes something like this:
select * from customer where division in ('D','I','2','3','C')
I need to pass the division 'D','I','2','3','C' part in because there
might be more divisions we need in the future or change of divisions,
we don't want to modifiy the package every time. So I set it in the INI
file like this and read it into a global variable:
[Customer]
Division = 'D','I','2','3','C'
But SQL doesn't recognize the SQL statement "select * from customer
where division in (?), where ? stands for the global variable. I tried
with setting Division = "'D','I','2','3','C'" in INI file, it still
doesn't work. The only way it works is to pass the 5 values as 5
seperate parameters and thus 5 global variables then the SQL statement
is like this:
select * from customer where division in (?,?,?,?,?)
But this defeats the purpose because I can't add another parameter in
the INI file without having to open the package and make changes.
Has anybody run into this before? Any suggestions is appreciated.
