SAS Data Libraries

An OpenVMS directory can contain many different types of files, including SAS files. All SAS files in a directory that are accessed by the same engine belong to a SAS data library. Thus, under OpenVMS, a SAS data library is a logical concept rather than a physical one.

Any OpenVMS directory can become a SAS data library when SAS files are stored in that directory; a single OpenVMS directory can contain several SAS data libraries. (See Multiple SAS Data Libraries in a Single Directory.) Also, under OpenVMS, several directories can constitute a single SAS data library if a search-string logical name is assigned to the series of directories. In Version 7, you can have concatenated libraries using a LIBNAME statement or LIBNAME function. (See Using a Search-String Logical Name to Concatenate SAS Data Libraries.)
