AI Summary: The issue describes a GDL (GNU Data Language) program with a `WIDGET_INFO` function that needs to handle several widget properties (e.g., `LIST_TOP`, `TEXT_TOP_LINE`). The task likely involves debugging or enhancing the `WIDGET_INFO` function to correctly retrieve and display information for these properties within the GDL environment. This might involve examining the existing code, understanding the GDL widget system, and potentially adding or modifying code to handle the listed properties.
