Maintaining the PASSWORD Data Set Using PROTECT

To use the PROTECT macro instruction, your PASSWORD data set must be on the system residence volume. The PROTECT macro can be used to:

Add an entry to the PASSWORD data set
Replace an entry in the PASSWORD data set
Delete an entry from the PASSWORD data set
Obtain a list of information about an entry in the PASSWORD data set; this list contains the security counter, access type, and the 77 bytes of security information in the data area of the entry.

The PROTECT macro also updates the DSCB of a protected direct access data set to reflect its protection status; this feature eliminates the need for job control language when you protect a data set.

PROTECT does not support data sets on dynamic devices.
