Data: Customer records and forms
The customer-related forms expose customer number, first and last names, company, address lines, city, state, ZIP code, and telephone information. The customer browse form displays full customer details, while the customer form binds the record through framework field and screen-record components. The telephone field uses the mask “###-###-#### XXXXX,” indicating a prescribed telephone-entry format in that form. These observations establish form structure, not necessarily persistence or event behavior for every field. E0003 E0004
State validation is documented as opening a scrolling list of valid states when the entered state code is missing or invalid. The available evidence does not independently establish the implementation of that interaction beyond the documented behavior and the presence of state-related application data. E0003 E0004
Harten documentation of the Informix 4GL and Java source repository, from the retained 17 October 2026 export. The exact upstream revision analysed is not established. Source findings do not establish runtime behaviour or equivalence between the implementations.
