The following list describes the major
features of the DATA step interface:
-
The DATA step interface enables you to access CA-IDMS data by traversing
the network using DML program functions calls. You cannot access data
through Computer Associate's Logical Record Facility (LRF).
-
The DATA step interface is a programming interface.
You do not have to create descriptor files to retrieve the CA-IDMS
data requested by your application.
-
Coding DATA step programs requires
knowledge of the database that is being accessed and the ability to
write host-level calls to retrieve CA-IDMS data. In order to provide
transparent access to CA-IDMS data, you can store compiled DATA step
programs as SAS DATA step views.
