This post introduces the hash iterator object. I will explain the basics of the object and show an example of how to iterate through a hash object.

This post demonstrates how to utilize the flexibility of PROC FORMAT by applying function logic to SAS formats with PROC FCMP.

When you use an array in a SAS data step, sometimes you need to reinitialize the array elements to some value. For example zero or one. Not long ago, I learned a nifty little trick that allows you to do so easily. This post demonstrates four different methods to set...

The aim of this post is to help you understand the Dosubl Function. I will present a few examples and explain how it differs from Call Execute.

This post shows an example of how to use a temporary array to store lagged values. This enables you to compute lags. Without the Lag Function.

This post demonstrates how to change formats, variables names and data set names dynamically in SAS with metadata and Call Execute logic.

Call Execute is a common routine in SAS. This post shows you by example how the SAS Call Execute Routine creates data-driven programs.
