/**
 Implements a text field that only accepts valid characters for an IBM i userid or password, with a maximum of 10 characters total.
 This text field will auto-uppercase any lowercase letters that are typed.
 It also rejects any characters that are not allowable in an IBM i userid or password.  The allowed characters are A-Z, a-z, 0-9, and the @, #, $, and _ characters.
 Up to 10 characters may be typed into this text field.
 Beeps are issued if the character limit is reached or invalid characters are entered.
 Note: This class becomes obsolete when the new password support becomes integrated into the IBM i.
