It seems the list of SAS preproduction is becoming shorter. Thanks for any inputs (just tested in SAS 9.3):
1. Output Data Step View (v.s Input Data Step View)
WARNING: The definition of an output DATA step view is an experimental feature in this release and is not intended for use in the development of production applications.
2. ODS Report Writing Interface (will turn to production in SAS 9.4?)
WARNING: DATA step interface is preproduction in this release.
