| SAS Companion for the CMS Environment |
SAS System Files lists all of the files that are frequently used by base SAS software. Under CMS, logical names are associated with most of these files. The logical names that are listed in the table are those that SAS uses by default. Your installation may use different names.
The system option column lists SAS system options that you can specify when you invoke SAS. You can use these system options to change the default settings that were established for your site. See Summary Table of SAS System Options for default logical names that are dynamically generated at SAS initialization.
The concat column specifies if the file can be specified as a concatenation of multiple files. For example, the SASHELP file can be specified as an ordered series of Help files using the SASHELP= system option. The default value for this option is 'SASHELP *'.
