The Change User Password 3 command allows a command change of a user password
that ensures the QPWDxxx system value requirements are met. For example, if you
have specified that a required digit exist by use of QPWDRQDDGT. This allows a
change to be made by other than the interactive user that still follows your
password requirements. CHGUSRPRF can change a password, but does not check the
system values.
