The default font of Code::Blocks has identical graphemes for O (the letter) and 0 (the digit). This causes confusion with variable names and so on.
Ideally I would just change one of those two characters to remove the ambiguity, but if necessary I can change the whole font used to display code. How would I do either one of these?
(It's a basic question I know, but there's not much here or in the wiki related to it - despite the wider problem being flagged as far back as Fortran).
