Changes a password or system password. Also, can establish a
    secondary password or system password, or remove a secondary
    password.

    A user password can contain up to 32 alphanumeric and special
    characters. Unless your system manager has set the PWDMIX flag
    in your authorization account record, the only special characters
    permitted are the dollar sign ($)  and underscore (_). Without
    the PWDMIX authorization, all lowercase characters are converted
    to uppercase before the password is encrypted. For example,
    "eagle" is the same as "EAGLE."

    If you have PWDMIX authorization, you can specify uppercase and
    lowercase alphabetic characters, and you can use any special
    characters in the printable character set. However, avoid using
    characters that have special significance for layered products
    that accept passwords. For example, a double quotation mark (")
    would be unacceptable in a password in a DECnet access control
    string.
