The COPY Procedure

Overview

The COPY procedure copies one or more SAS files from a SAS data library.

Generally, the COPY procedure functions the same as the COPY statement in the DATASETS procedure. The two differences are as follows:

The IN= argument is required with PROC COPY. In the COPY statement, IN= is optional. If omitted, the default value is the libref of the procedure input library.
PROC DATASETS cannot work with libraries that allow only sequential data access.
