IDL

The programming IDL, or interface definition language, is a computer language used to create and define the parameters and functions of software objects. It allows software developers to create a standard interface for their programs, which can then be used by other developers to create compatible programs. This makes it easier for program users to find and use software that meets their needs, as they can search for programs that have been created using the same IDL. Additionally, it can help ensure compatibility between different software versions, as any changes made to the interface definition will be automatically reflected in all programs that use it.
