Indexes
-
If a data set has an index on the variable
or variables named in the BY statement that accompanies the MERGE statement,
then you do not need to sort that data set. For more information about indexes,
see
SAS Language Reference: Concepts and the
Base SAS Procedures Guide.

SAS date and time formats and informats

The examples in this section read Time as
a character variable, and they read Date with a SAS date informat. You could
read Time using special SAS time informats. For more information about SAS
date and time formats and informats, see
SAS Language Reference: Dictionary.
