SAS system options are instructions that affect your SAS session. They control how
SAS performs operations, such as SAS system initialization, hardware and software
interfacing, and the input, processing, and output of jobs and SAS files. The
SPD Engine system options work the same way as SAS system options. This section discusses system
options that are used only with the SPD Engine, and Base SAS system options that behave
differently with the SPD Engine.
