I’m very much guessing that this is just supposed to be a type of pseudocode given the context and vagueness of it.
It’s a big reason why I really dont like pseudocode as instruction to people learning the basics of what programming is. It made more sense 20 years ago when programming languages were on a whole a lot more esoteric and less plain text, but now with simple languages like Python there’s simply little reason to not just write Python code or whatever.
I took an intro to programming class in College and the single thing I got dinged on the most is “incorrect pseudocode”, which was either too formal and close to real code or too casual and close to plain English.
It’s not a great system. We really need to get rid of it as a practice
