PROC RELEASE will abend whenever you attempt to process an extended format sequential data set. At SAS^® 9.2 (TS2M2) under z/OS V1R10, a message like the following appears on the SAS log:

ERROR: System abend 213 occurred outside of the SAS environment.
ERROR: Delete current task.

IEC143I 213-B8,
IFG0194D,XXXXXX,LOGON,EXTFMT,4019,SMS010,XXXXXX.EXTFMT.SASLIB.V9TAPE

This error occurs because PROC RELEASE uses an EXCP mode DCB to process the data set, but EXCP is not supported for extended format data sets.

To avoid this error, do not use PROC RELEASE on extended format data sets.
