Code	Purpose

A	Allows alphabetic characters only.
L	Allows logical data only.
N	Allows letters and digits only.

$	Displays the current currency symbol specified by SET CURRENCY.

character (SET SEPARATOR) and the decimal character (SET POINT) can all be 
changed.  Can only be used in @ ... GET when SET CURRENCY is LEFT.
*	Asterisks are displayed in front of a numeric value.  Use with a dollar sign $ for check protection.
