Accessing SAS Catalogs

Note:   The engine that creates a SAS catalog determines its format, which is different in Version 6 and Version 8 and therefore not compatible. However, the format of a SAS catalog entry is determined by the SAS program or application that creates it and may or may not be compatible between versions.  [cautionend]

Using Version 8 to Access Version 6 Catalogs without Converting

Version 8 can read a Version 6 catalog. Therefore, if you do not need to update a Version 6 catalog, then you do not need to convert it.

In general, Version 8 cannot write to a Version 6 catalog. However, you can use the COPY procedure to write a Version 6 catalog from a Version 6 library to another Version 6 library.

Version 8 cannot create new entries or update existing entries in a Version 6 catalog. You must convert the catalog to Version 8 format.

Version 6 cannot access Version 8 catalogs, because the file formats are not compatible.

Converting Version 6 Catalogs to Version 8 Format

For a Version 6 catalog, to create new entries or to update existing ones, you must convert the catalog to Version 8 format. Two methods are available, which produce different results regarding catalog entries:
