Let's talk about looping, first. I'm going to create a new project, and it would be an integration services project. Default name, default location, and here on the Control Flow surface, I'd like to look at the For Loop Container. Over here on the right, in the Toolbox, I have the For Loop Container. I'll drag one of those onto the Control Flow surface, and I'll need to set up some initial conditions about the For Loop.
