Alpha Anywhere supports Coded Fields, a field that displays one value but internally stores another value. For example, a product_id field might store "X123" internally, but display "Alpha Five V5" on Forms, Reports, etc. To define a coded field, you perform the following steps:
Define a Table Lookup Field Rule for the field.
Check Display as a drop-down list box.
The field for which the lookup rule is defined must NOT be displayed in the lookup.
