Example 8. DTS: Transferring Numerics by Using the EXTENDSN= and V6TRANSPORT Options

Purpose

For releases prior to Version 7, when transferring short numerics (length less than 8) the length of these numerics is automatically increased to preserve precision. In Version 7 or Version 8, the length of these numerics are increased by default unless the V6TRANSPORT option is specified. Using the V6TRANSPORT and EXTENDSN= options in PROC UPLOAD and PROC DOWNLOAD statements, you have the choice of whether or not to promote the length of numerics.

Programs

Example 8.1: Using the EXTENDSN= and V6TRANSPORT Options in the PROC UPLOAD Statement

This example uploads the data set A in the directory WORK on the local host to the directory REMOTE on the remote host. The V6TRANSPORT option causes the short numerics to be promoted; therefore EXTENDSN=NO must be specified to override this default, so that numerics will not be promoted.

proc upload data=a out=remote 
   v6transport extendsn=no;
run;

Example 8.2: Using the EXTENDSN= Option in the PROC DOWNLOAD Statement

This example downloads the catalog SCAT in the directory REMOTE on the remote host to the directory WORK on the local host. By default, catalog transfers promote the length of short numerics within SCREEN entry types. This behavior can be overridden by specifying EXTENDSN=NO on the catalog transfer download. The EXTENDSN= option is supported by catalog transfer of SCREEN entry types only.

Note: The V6TRANSPORT option is not needed when transferring a catalog. [cautionend]

proc download incat=remote.scat outcat=work.scat 
   extendsn=no;
run;
