Attention : This code requires administrator privileges.
The script begins by initializing a CAS session and assigning all available CAS libraries. It then sets the default active CASLIB to 'public'. The `PROC FORMAT` procedure is used to create a custom format ('dow' for days of the week) and save it to a CAS format library named 'casformats' using the `CASFMTLIB` option. `cas casauto` actions are then executed to save and promote this format library, ensuring its persistence and availability across CAS sessions. The script also includes a `PROC CAS` block that allows assuming an administrative 'SuperUser' role to modify server options. The `fmtsearch` option is updated to include the new 'casformats' library, which ensures that custom formats can be found and used by client applications, such as SAS© Visual Analytics. A check of the `fmtsearch` option is performed to confirm the change.
Data Analysis
Type : CREATION_INTERNE
The data (the 'dow' format) is created directly within the SAS script via the `VALUE` statement of `PROC FORMAT`. No external data or data from predefined libraries (like SASHELP) is used as a source for format definition.
1 Code Block
CAS Session Management
Explanation :
This block initializes a CAS session and assigns all available CASLIBs. It then sets the default active CASLIB to 'public' via the `options caslib=` statement, which influences where subsequently defined formats will be written or searched for.

PROC FORMAT Data
Explanation :
This `PROC FORMAT` procedure defines a user-defined format named 'dow' that associates numeric values (1-7) with the names of the days of the week. The `CASFMTLIB="casformats"` option specifies that this format should be stored in a CAS format library named 'casformats', thus making it available in the CAS environment.

CAS Actions
Explanation :
This block uses `cas casauto` actions to manage the CAS format library. `savefmtlib` saves the 'dow' format to the 'casformats' library. `promotefmtlib` makes this format library available to all active CAS sessions. Finally, `listfmtranges` displays the details of the 'dow' format to verify its existence and configuration in CAS.

PROC CAS (Administration)
Explanation :
This `PROC CAS` block is used for administrative tasks. It first assumes a `SuperUser` role to allow modifications to CAS server options. Then, it uses the `configuration.setServOpt` action to modify the `fmtsearch` option, adding 'casformats' to the format search path, which is crucial for applications like SAS Visual Analytics to find and use formats defined in CAS. Finally, `configuration.getServOpt` is used to verify that the option has been updated.
