Lingo is a high-level programming language developed by Macromedia. It is used primarily for authoring multimedia content for the web, although it can be used to create stand-alone applications as well.
Lingo is based on the concept of objects and actions. Objects are the things that you manipulate in your code, and actions are the things that you do to them. For example, you might have an object representing a button on a web page. You would then write code to perform actions on that button, such as making it visible or invisible, or changing its color.
Lingo is a very powerful language, but it is also easy to learn. It has a syntax that is similar to English, so it is easy to read and write code in Lingo.
If you are interested in learning Lingo, there are a number of resources available on the web. You can find tutorials, code examples, and more.
