Create User Defined Functions (UDFs) for the CAS Server on SAS Viya Welcome back to my SAS Users blog series CAS Action! - a series on fundamentals. In this post, I'll show how to create user defined functions (UDFs) for the distributed CAS server using SAS and CASL code. Once the...
1. As a macro function, you do not need to enclose character values in quotation marks as you do in DATA step functions. One way in which macro langu.
