Password protection specification - Key = '0020'

DALPASPR specifies that the data set being created is to be password protected. It is mutually exclusive with the SYSOUT (DALSYSOU) key. When you code DALPASPR, # and LEN must be one, and PARM contains one of the following values:
X'10'
The data set should not be read, changed, extended, or deleted without the password.
X'30'
The data set should not be changed, extended, or deleted without the password. Reading is permitted.
Example: To specify complete password protection,: code
KEY   #     LEN   PARM
0020  0001  0001  10
