The SET option lets
you define an environment variable that is valid within the SAS session
and any shell started from within the SAS session. Using the SET
option is similar to using the SAS
setenv command.
For information about executing system commands from within your SAS
session, see
Executing Operating System Commands from Your SAS Session.
A special use for the
SET option is to specify the name of the
!SASROOT directory:
-set SASROOT pathname
The
pathname specified can then be used to expand
!SASROOT
(as shown in
Character Substitutions in Pathnames).
After exiting your SAS
session, environment variables that are set with the SET option no
longer exist.
