X++

Axapta inherently begs community involvement from X++ developers due to its horrible lack of documentation. Dynamics Ax 4.0 (the erp system formerly known as..) certainly solves this to great lengths, but there are still grey-areas here and there which need to be filled in.

I often get asked about tips and tricks in Axapta, and today I was asked (again) about the nofetch keyword in X++ select statements. Why is it there? What's the point?
