Here's a couple of examples of RPGIII programs (SQLRPG) that return result sets. It works fine in ILE RPG too but I haven't got an example handy. RPG code for program TEST01QA (compiled using CRTSQLRPG on a box with the licensed program 5769ST1 DB2 Query Mgr and SQL DevKit for AS/400 loaded - this is not required at run time).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
