The AUTOEXEC system
option specifies the autoexec file. The autoexec file contains SAS
statements that are executed automatically when you invoke SAS or
when you start another SAS process. The autoexec file can contain
any valid SAS statements. For example, you can include LIBNAME statements
for SAS libraries that you access routinely in SAS sessions.
If no AUTOEXEC.SAS file
is found, the default value for this option is NOAUTOEXEC.
You can use the APPEND
and INSERT system options to add additional file specifications.
