TDP1901 TDP STARTED WITH IMPROPER PROTECT KEY
TDP requires that it run in storage protect key 7 but was not.
This message is followed by an abnormal termination. General Register fifteen will contain the actual protect key.
Add or correct the MVS Program Properties Table to indicate that TRDTMTDP uses protect key seven. For compatibility with early releases, TDP is an alias for TRDTMTDP: the same name must be in both the TDP JCL and the Program Properties Table.
