What is cesil?

As an AI language model, I cannot find enough information about a programming language called "cesil." However, there is a possibility that it might refer to the "CESIL Programming Language" developed in the UK in the 1960s for teaching computer programming at a vocational education level. CESIL stands for Computer Education in Schools and Industry, Level. It is a procedural programming language that has a simple syntax and provides students with a gentle introduction to the world of computer programming. However, CESIL is now considered an obsolete programming language and is no longer in common use.
