Computation Layer language

What is the programing language that the CL is based in, or what is a language that is close to the CL language ?

I don’t know the correct answer other than that it was not an existing language. However, the best answer I heard when I kept trying to compare it to different languages was to think about it more like a spreadsheet than the other languages I was mentioning. Thinking of it as a spreadsheet (constant updates and computation dependencies rather than sequential code) helps me to understand the error messages a lot better.
