Initializing and Configuring SAS Software

Using Input/Output Features

SAS 5 and SAS 6 data sets generally need to be migrated to SAS 9.2 to enable you to use the I/O features introduced in SAS 9 and SAS 8. For example, to add integrity constraints to a SAS 6 data set, you must first migrate that data set to SAS 9.2. For information about migrating your data sets, see the Migration focus area at support.sas.com/migration. For information about I/O features introduced in SAS 9, SAS 9.1, and SAS 9.2, refer to the SAS Language Reference: Dictionary.
