The CALL PROCESS limitation has been removed from 4D Server 2004.6. For example, if you want to display a progress bar or clock in 4D Server, you had to display a dialog and use the On Timer form event to update your variables. This was increasing the CPU usage. With 2004.6, your process can now request an automatic update by performing an On Outside Call on that dialog. In your dialog, you can check for the Outside call event and perform a redraw or close that dialog if needed.
