Terminating the Protection Feature Process

Processing is terminated if:

The operator cannot supply the correct password for the protected data set within two attempts.
A password record does not exist in the PASSWORD data set for the protected data set being opened.
The protection-mode indicator in the password record and the method of I/O processing specified in the open routine do not agree; for example, OUTPUT specified against a read-only protection-mode indicator.
There is a mismatch in data set names for a data set involved in a volume switching operation. This is discussed in the next paragraph.
