SAS 9.1 Language Reference Concepts

Because of the restrictions, it might not be feasible to use CEDA. You can use the following methods in order to move files across operating environments:

XPORT engine with the DATA step or PROC COPY

• In the source environment, the LIBNAME statement with the XPORT engine and either the DATA step or PROC COPY creates a transport file from a SAS data set. In the target environment, the same method translates the transport file into the target environment's native format. Note that the XPORT engine does not support SAS 7 and later features, such as long file and variable names .

XML engine with the DATA step or PROC COPY

• In the source environment, the LIBNAME statement with the XML engine and either the DATA step or PROC COPY creates an XML document from a SAS data set. In the target environment, the same method translates the XML document into the target environment's native format.

CPORT and CIMPORT procedures

• In the source environment, PROC CPORT writes data sets or catalogs to transport format. In the target environment, PROC CIMPORT translates the transport file into the target environment's native format.

Data transfer services in SAS/CONNECT software

• Data transfer services is a bulk data transfer mechanism that transfers a disk copy of the data and performs the necessary conversion of the data from one environment's representation to another's, as well as any necessary conversion between SAS releases. This requires that a connection be established between two SAS sessions by using the SIGNON command and then executing either PROC UPLOAD or PROC DOWNLOAD to move the data.

Remote library services in both SAS/SHARE software and SAS/CONNECT software

• This gives you transparent access to remote data through the use of the LIBNAME statement.
