The DATA step hash object enables efficient data storage and retrieval. The hash iterator retrieves data sequentially from a hash object. The hash object and hash iterator are production in SAS 9.1 (preproduction in SAS 9.0).
The DATA step Java object is used for running Java code from the DATA step. See The Java Object and the DATA Step Component Interface (March 2008). The DATA step Java object is production in SAS 9.2. It was preproduction in SAS 9.0 and 9.1. This documentation is updated for SAS 9.2.
