In SAS Studio, the SAS system option VALIDMEMNAME is set to EXTEND by default. The names of SAS data sets (tables) can include national characters and other special characters, except for the / \ * ? " < > |: -. characters. The length of a table name is limited to 32 bytes.  

CAS table names can include national characters and have no length limitation. CAS table names can also include special characters, such as a hyphen (-).

CAS tables that do not comply with the VALIDMEMNAME rules do not appear in the Libraries tree structure in SAS Studio.

To view the tables in the SAS Studio Libraries tree, you must rename the CAS tables so that they comply with the VALIDMEMNAME rules. You can change the names within other SAS^® Viya^® products, such as SAS^® Environment Manager and SAS^® Data Explorer.

Note: You can access the tables by using code for the CASUTIL procedure and through Cloud Analytic Services Language (CASL) actions within the CAS procedure in SAS Studio. However, the tables cannot be accessed by Base SAS^® procedures that are CAS-enabled.
