RE: SQLRPGLE - Dynamic selection

["Tracy Ball" <TBall@xxxxxxxxxxxxxxxx>]

Does the nulls field have any bearing on the syntax here at all?  This is a 
great example.  From what I can see, I am doing pretty much all these things in 
just a much simpler text, yet don't get the results.   

I will use this as a model.  Thank you very much!!

something like this:

     D itnbr                         15    CONST

     PgetItemData      B                   Export
     DgetItemData      PI            40
     D itnbr                         15    CONST
     D year                           4  0 CONST

     ditemDS           ds
