The MKD command was issued to create a new PDS. The SITE RECFM parameter had a value of recfm, which is not a valid record format for a PDS.
The MKD command is rejected. Control is returned to the client connection for further command processing.
Issue the SITE RECFM command to change the setting of RECFM to a record format that is valid for a PDS, then reissue the MKD command. (Incorrect record formats are FBS, VBS, and VS).
None.
