Data Set Password . . (If password protected)The Data Set Password field contains the password for OS password-protected data sets. By assigning more than one password to the same data set, you can give some users read-only access while giving others read/write access.
Nondisplay input fields are used so that the passwords do not appear on the screen. When you specify a concatenated sequence of libraries, the password applies to all data sets in the sequence.
If you replace a long password with a shorter password, blank out the remaining spaces of the Data Set Password field.
You can use ISPF with the Resource Access Control Facility (RACF®). RACF provides extensive facilities for data set security. However, when using RACF, do not enter a password on the ISPF panels, because RACF relies on your TSO user ID and logon password to identify you and check for proper authorization.
