Hi all A couple of years ago I did a lot of research into the programming aspects in SAS Viya 3, including CAS sessions, libraries, engines.  Also, the use of CAS Actions and CAS Action sets. I'm now looking at Viya 4 and wondering if there any major (or minor) differences when programming (specifically) in Viya 4. Has the terminology changed ?  In Viya 3 there was reference to a SPRE - is this now referred to differently , and does it still exist ?   There's a lot of documentation out there, but it would be great if someone could point me to any differences I should be aware of. Thanks in advance Dave ... View more
