Syntax

SAS-data-set: specifies a SAS data set name.

Restriction:No data set options are allowed.

Tip:Use libref.membername or membername syntax, not a string that is enclosed in quotation marks, to specify a SAS data set name. You can use quotation marks in the libref.membername or membername syntax if the libref or member name is associated with a SAS/ACCESS engine that supports member names with syntax that requires quoting or name literal (n-literal) specification. For more information, see SAS/ACCESS for Relational Databases: Reference.

By default, SAS automatically keeps track of the most recently created SAS data set. Use the _LAST_= system option to override the default.
