The Facelift Process
1) As you step thru the host forms, they are captured on disk
2) Using the captured data, identify unique forms
index.cfg
4) Using your favorite HTML editor, modify Gweb HTML, or create your own. All fixed/variable data from the host screen is available. Macros can skip display of specific screens.
3) A facelifting configuration file is created or updatedgwebedit.exe
Write HTML to Replace the Default Form
The original screen contents, including input fields, are available for use
Buttons, optionally with your own text, for emulation function keys or macros
