Params itemnumber is the number of a dialog item in a dialog defined using Macintosh resources.
Action Sets the value of the indicated dialog itemnumber to val.
This verb is only implemented in the Mac OS version of Frontier. If itemnumber is out of range for the dialog, an error results. This is an advanced Frontier verb of primary interest to implementers and advanced scripters. It is not necessary to understand it to use Frontier effectively for most tasks. This verb only works if there's a dialog box displayed.
