PS: In a 21-CFR-11 app fixing that would require a recompile and all functions using it be recertified. Lets say we follow the example of ancient Hebrew and just leeve the vowels out?
I found a typo in a file save routine in one of my projects and corrected it (nobody had complained about it). Yesterday, I deployed the code to the customer. Took me some time debugging until I found, that the typo was still in place in a file parser routine.
Lesson learned, leave the typos (sometimes ignore spell-checkers when writing the documentation), spend the time on real bugs and features.
