Unique, Mod & Div - Three powerful techniques for record ranges (Free Video)
No preview video available.
It was just the other day when I was scripting loops for processing a range of records - you remember writing those loops, don't you? But then it occurred to me, (without talking to my mathematician friends) if I knew about the Mod function what would Div do for me and my range of records? As is usually the case, math was the solution and I finally realized what it meant to my files.
Math may not be my strongest subject, but having that "Ah ha" moment sure does feel triumphant. This video may help you with understanding the math around the records in your found set!
