BTS0009W SYNAD ERROR OCCURRED DURING READ OF INPUT DATA SET.

Explanation
 An uncorrectable input or output error was detected
by the operating system for the input (BTSIN) data set. IMS Batch Terminal Simulator stops processing
the current transaction at this point and does not issue a dump.

System action
 IMS Batch Terminal Simulator returns an AQ
status code to the application program if
the message GU was in process.  Otherwise, IMS Batch Terminal Simulator simply ends.

User response
 Check the JCL or the BTS
CLIST to see that the
BTSIN data set is correctly specified and rerun the job.
