SAS Companion for the CMS Environment

SAS Files and SAS Data Libraries

Under CMS, a SAS file is a specially structured CMS file. SAS files are logically grouped into SAS data libraries. A SAS data library can reside either on a CMS minidisk, in an accessed Shared File System (SFS) directory, or in an unaccessed SFS directory. An accessed SFS directory is one that you have identified to the operating environment with the CMS ACCESS command.

The logical grouping of a SAS data library is done according to filetype and filemode or directory. That is, files that have the same CMS filetype in a minidisk or in an SFS directory are members of the same SAS data library.

Note: The term disk is used to refer to both a minidisk and an SFS directory. [cautionend]
