Usage Notes
After a Read method (“Read function” on page 904) on the Screen object, you use the Value method to get any user-entered data for a non-protected field.
For an example using Value to set field display data, see “Screen class example”. For an example using Value to get user-entered data, see the example below.
See also the AddField method, whose Value parameter can set display data when the ScreenField is instantiated.
