My experimental spreadsheet does something like this. You can refer to the value of a cell given some different values in other cells, and it calculates the value of the cell given just those changes. Syntax is cellname{othercell=othervalue, ...}. So you can use a group of cells like a function with parameters (with defaults). Fizzbuzz example: https://visibot.com/webdemo/#/%2Fexamples%2Ffizzbuzz.vb https://visibot.com/webdemo/#/%2Fexamples%2Ffizzbuzz.vb Use right and left arrow keys to scrub through the program's execution. The help link in the NE corner gives more details. (This is still evolving, and uses WASM to run in the browser so it's desktop only. LMK if it doesn't work for you.)
