CMS filetypes That the SAS System Uses

Unless you specify otherwise, SAS assumes default filetypes for the CMS files that it reads and writes. SAS uses the following default CMS filetypes:

LISTING

for output from SAS procedures. The filename of the LISTING file matches the filename of the file that contained the SAS program.

SAS

for a file that contains SAS statements. You assign this filetype when creating a file that contains SAS statements, including your autoexec file and files that contain SAS programs. Configuration files and autoexec files are discussed in "Configuration Files" on page 12 and in "Autoexec Files" on page 13.

SASLOG

for the SAS log and messages. The filename of the SASLOG file matches the filename of the file that contained the SAS program.

SAS uses the CMS filetype to form a logical grouping called a SAS data library. SAS uses the following filetypes for special SAS data libraries:

• LIBRARY

• SASHELP

• SASUSER

• WORK.
