Abstract

This paper discusses how you cope with the following data scenario: the input data set is defined in so far as the variable names and lengths are fixed, but the content of each variable is in some way uncertain. How do you write a SAS program that can cope appropriately with data uncertainty?

“Code doesn’t care who wrote it, but it does matter how well it was written!” — Gavin Winpenny (2017)
