The DISK option is the default for the CIMPORT procedure. Therefore, PROC CIMPORT defaults to reading from a file on disk instead of from a tape. If you want to read a file from tape, then specify the TAPE option.
When writing and reading files to and from tapes, you are not required to specify the DCB attributes in a SAS FILENAME statement or FILENAME function. However, it is recommended that you specify BLKSIZE=8000.
Note: Starting in SAS 9.1, you can use the MIGRATE procedure to migrate a SAS library from a previous release. For more information, see the Migration focus area at support.sas.com.
