![Data tables: Nonmatrix data structures in SAS/IML](https://blogs.sas.com/content/iml/files/2017/01/ProgrammingTips-2.png)
Prior to SAS/IML 14.2, every variable in the Interactive Matrix Language (IML) represented a matrix. That changed when SAS/IML 14.2 (released with SAS 9.4m4) introduced two new data structures: data tables and lists. This article gives an overview of data tables. I will blog about lists in a separate article.
