Get Zoom Return Field hook

Use this hook to specify the field that must be returned of the selected record in the zoom session and specified in the custom field. It must be one of the fields that are shown in the zoom session.

Example:

function extern string ext.colr.f.get.zoom.return.field()
{
        return("txcpr001.colr") }

This hook is called after the form is loaded in the session. If the zoom return field depends on the data in the session, use this hook to set the default zoom return field. The specific zoom return field that is based on the data must be set in the Before Zoom hook.
