Re: Get next Tuesday. Or the one after

["Lennon_s_j@xxxxxxxxxxx" <lennon_s_j@xxxxxxxxxxx>]

Don't know if I totally understand your requirements, but you can easily 
get the week of the year with SQL:

select week(current date) from sysibm/sysdummy1

"The WEEK function returns an integer between 1 and 54 that represents 
the week of the year. The week starts with Sunday, and January 1 is 
always in the first week."

But I suspect that this definition of week number may not suit your 
requirements.

You can get back a 0 or 1 from an SQL expression like this:

select mod(
           (days(date(current date)) -
            days(date('2010-01-05'))
           )/7
         ,2)
from sysibm/sysdummy1

and if you combine something like the above with dayofweek(current date) 
that might be what you want.

It's not very clear what is going on, so the algorithm might be better 
in RPG.
