About this Program…

Have you noticed the item in the Help menu – “About this Program…” – that is usually grayed out? It’s reserved especially for your own project. Just define a procedure named ABOUT and Logo will automatically assign it to this menu item.

Any procedure will do, but for a short, popup message, the ALERT command works best. Look for examples in other projects here in the Logo Library.
