Verify Operation (Magic xpa 4.x)
The Verify operation is a client-side operation. You can use it to display messages to the user in a dialog box, or on the status bar.
If you choose to display a message using Display=Status, keep in mind that the status bar will be the status bar of the SDI window. If you aren't using an SDI window, then the message won't display. If you use Display=Box, then a popup box will appear, as it would in an ordinary online program.
Because the Verify operation is client-side, you can't use it in the Task Prefix logic unit in a non-Offline task.
