SAS: session

SAS assigns a work library.

The sashelp library is made available. Its views and tables contain metadata on the session.

The sasuser library is checked for a profile catalog

The autoexec.sas file is executed.

Apparently, when the session is started, a sas.lck file is created in this work directory

The work library is cleaned up (except when a SAS session crashes, in which case the work directory should be manually cleaned up).

utf 8 sessions

Recovering an interactive session

Option presenv and proc presenv to preserve some settings across sessions.
