I can't find a proper source for this but many materials say that ANSI rows and columns start at 1 not 0. https://www2.math.upenn.edu/~kazdan/210/computer/ansi.html is as good as I can get: ``` <row> is a number from 1 through 25 that specifies the row to which the cursor is to be moved. <col> is a number from 1 through 80 that specifies the column to which the cursor is to be moved. ``` 0 does work in Windows terminal and Linux terminals, but we might as well be correct and it's one less thing to reason about when auditing this code. From what I read, some terminals correct 0 back to 1 and some treat 0 as a missing argument, which also defaults to 1.
