One advantage of the
SAS/ACCESS interface to SYSTEM 2000 is that it enables SAS to read and write SYSTEM 2000 data
directly, using SAS programs. This section presents examples of using SYSTEM 2000
data that is described by
view descriptors in SAS programs. For information about the example data, see
Example Programs. For information about using view
descriptors efficiently in SAS programs, see
Performance Considerations. Throughout
the examples, the SAS terms
variableand
observation are used in place of comparable SYSTEM 2000 terms because these examples illustrate
using SAS procedures and the DATA step. The examples also include printing and charting
data, using the SQL procedure to combine data from various sources, and updating
a SAS 7
data set with data from SYSTEM 2000. For more information about the SAS language and procedures
used in the examples, see the documents referred to throughout this section.
