SAS Catalogs

Definition of a SAS Catalog

SAS catalogs are special SAS files that store many different kinds of information in smaller units called catalog entries. Each entry has an entry type that identifies its purpose to SAS. A single SAS catalog can contain several types of catalog entries. Some catalog entries contain system information such as key definitions. Other catalog entries contain application information such as window definitions, help windows, formats, informats, macros, or graphics output. You can list the contents of a catalog using various SAS features, such as SAS Explorer and PROC CATALOG.
