That so, I have used the vocabulary/phrasing in my code, like here (defun isbn--char-to-int (c) "Convert a char C into the integer it displays, e.g. 9 for ?9." (- c ?0) ) does that mean I should change that into ditto number on might wonder? https://dataswamp.org/~incal/emacs-init/isbn-verify.el There is also the mention of "digit" all the time ... but that's in the Emacs regexps so can't be all bad. The word "bit" = "binary digit" BTW, not ditto "in----r" as many people think. But the `pi' isn't pi in Emacs anymore but `float-pi'!
