Modifying SAS Data Sets This example illustrates the modification of two SAS data sets using the MODIFY statement and its sub-statements. It shows how to: modify SAS files, label a SAS data set, add a read password to a SAS data set, indicate the current sort order of a SAS data set, create an index for a SAS data set, assign informats and formats to variables, rename variables, and label variables in a SAS data set.	ETL
OUTPUT Statement Writes the current observation to a SAS dataset.	Action CAS
PROC CASUTIL The CASUTIL procedure offers several table and caslib management functions, including displaying table metadata, deleting files, unloading and loading tables, promoting tables, and saving tables.	ETL CAS
Default SAS Libraries This document describes the default SAS libraries: Work (temporary), User (user), Sashelp, and Sasuser. It explains their role and behavior within the SAS Viya 4 environment.	Data Access
SAS Viya Platform File Service The SAS Viya Platform File Service allows storing, retrieving, and deleting files kept in the SAS Infrastructure Data Server database repository. This repository is not considered a complete 'file system' but contains individual files directly accessible by their file identifier (UUID).	Administration
User-Defined Formats In the SAS Viya platform, you can store user-defined formats in catalogs for use in a SAS session, or you can store them in a format library on the CAS server. Format libraries are associated with a CAS session, or they can be promoted to global scope to be available to all CAS sessions. User-defined formats in a format library are server-side formats that the server uses when an analysis is performed based on formatted values. You can migrate existing user-defined formats from SAS to the SAS Viya platform.	Tools CAS
Sans titre Defines one or more indexes for a new output SAS data set.	Général
KEEP Statement Specifies variables to include in output SAS data sets.	ETL CAS
SAS Library Concatenation Explains the concept of SAS library concatenation, allowing several libraries to be logically grouped under a single reference (libref).	Data Access
Examples: Using a SAS Engine to Process External Data This document provides examples of using SAS engines to access and process various types of external data, including delimited files, Excel files, databases (DBMS), XML, and JSON.	Data Access
