PASSWORD(<expC>)
 Stores a password so that it cannot be read.
 Returns <expN> in the range from eight to ten digits.

 <expC> may contain spaces and non-alpha characters.
 Distinguishes between uppercase and lowercase.

 Returns zero if <expC> is less than 3 characters.

 Useful in applications that require one or more levels
 of password protection.

 <expN> cannot be decoded to reveal the <expC> that created it.
