I recently recorded a short video about the new syntax for specifying and manipulating lists in SAS/IML 14.3. This is a video of my Super Demo at SAS Global Forum 2018. The new syntax supports dynamic arrays, associative arrays ("named lists"), and hierarchical data structures such as lists of lists.

If your browser does not support embedded video, you can go directly to the video on YouTube.

If you prefer to read about lists, the following references provide more information and additional examples of ways to use lists:
