When you are running SAS^® software in the z/OS operating environment, you might encounter an abort error under the following circumstances:

• You are accessing a partitioned data set extended (PDSE).
• You are not using the Large Block Interface (LBI).
  Note: LBI is the default interface used for disk and tape files. However, you can disable this interface by using the SAS system option NOFILELBI. LBI might also not be used if the operating system finds that LBI is not supported for the file at OPEN time.

When you encounter this problem, the BLKSIZE that you originally set for the data set is changed to an invalid BLKSIZE. Then, you receive an error similar to the following:

In the error message above, the data set was originally allocated with BLKSIZE=27920. However, the error indicates that BLKSIZE=486672.
