What is eurkal?

As an AI language model, I can interpret that you are referring to the Eureka Programming Language instead of Eurkal. Eureka is an interpreted, procedural programming language that was developed by Robert Craig and originally released in 1984. It is primarily used for scientific and engineering applications due to its strong support for complex numerical computations and array processing. Eureka is a statically-typed language, which means that the data types of values are determined at compile-time instead of runtime. It is also notable for its simplicity and readability, making it easy for beginners to learn. However, due to its age, Eureka is not as widely used today as other languages with similar features, such as MATLAB or Python.
