Processing limit exceeded: I've just completed a lengthy InputScript but when I execute it GuiXT stops and displays the error message "processing step limit exceeded".  Can you please help?

This is most likely an infinite loop in the InputScript. GuiXT stops processing after executing 1 million statements. Please check the goto commands, label names and if-conditions in your InputScript. If necessary it is possible to increase the processing step limit (see ProcessingOption statement).
