SAS®9 Processing of SAS 6 Files via the V6 Engine

If you do not migrate SAS 6 files to SAS®9 format, the V6 compatibility engine can automatically process some files. This topic describes the supported processing.

Processing Compatible Files

The V6 engine provides the following processing for compatible SAS 6 files. Use the Compatibility Calculator to determine whether your files are compatible.

Read-Only Processing of Incompatible Files for Selected Environments

The V6 engine provides the following processing for incompatible SAS 6 files under selected environments. Use the Compatibility Calculator to determine whether read-only V6 processing is supported for your files.

Using the V6 Engine

If you do not specify an engine name, and the location contains only V6 files, SAS automatically assigns the V6 engine. However, it is suggested that you specify the V6 engine name:

   libname myfiles v6 'v6-SAS-data-library';

Note: The V6 engine processes Version 6 files created by Release 6.08 through Release 6.12. For Version 6 files prior to Release 6.08, see the SAS documentation for your operating environment.

Creating Version 6 Files in SAS®9

You might need to create (output) a Version 6 file in a SAS®9 session, for example, if you are sharing data with a Version 6 application. To do so, see the information about regressing a file to Version 6. Keep in mind that the Version 6 file must adhere to Version 6 capabilities, that is, no long names, no integrity constraints, and so on.
