In the initial release of InfoPath 2003, the coding environment is the Microsoft Script Editor.
The Script Editor provides a Document pane to aid with code creation and editing.
The Document Outline pane allows easier navigation among functions and/or subroutines in the open script file.
The Script Editor provides summary information about the InfoPath object model in the Object Browser.
The Script Editor supports debugging functionality to help identify the sources of error messages.
JScript or VBScript can be used in script files for InfoPath templates.
The Microsoft XML Core Services 5.0 (MSXML 5.0) provides an XML processor for InfoPath 2003 and allows the developer to have programmatic access to the DOM of the form template data source.
