Using Engines with SAS/GRAPH Software

In SAS, procedures use engines to access data. Characteristics of these engines vary; generally, they enable SAS procedures to access a data library in a particular way. Engines can specify the expected format for the SAS data file, the type of read or write activity that can occur in SAS data files, and so on. In most cases, you use the default engine for the current SAS version and do not need to specify an engine.
