4.3.3 Password routine

-----------------------

Enter Password 'T' 'A' 'I'

-----------------------

If the password is 'TAI' then the letters 'T' 'A' 'I' will be supplied to the user when this screen is entered. This is an 'easy guess' password. If the password is any other string, then the letters 'A' 'A' 'A' will be supplied regardless of the actual password. The user must then adjust the letters to the correct password.

Pressing ENTER advances to the next letter. When at the 3rd letter, Pressing ENTER causes the letters to be compared to the actual password. If the letters don't match, the user is told 'Password Incorrect'. If the letters match the password, then all menu items now become available and the user is offered the chance to change the password by means of the following screens.

-----------------------
