| 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
listed in the table are those that SAS uses by default. Your installation
may have changed these 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.
