Comments in code??
Surely you jest...
The current project I'm working on dates back to the 60's (so I'm told, and I believe it!). It is a giant group of Fortran programs (remember those) that have been pieced together step by step to produce an income generating system (yes, money is made on it!). Now nice people like me are brought in to add features to it, or otherwise alter the code, and while I pride myself in being a reasonably competent programmer, I wonder how this code ever got off the ground. Comments are few and far between, and most of the code (including some recent additions in C) look like they have been written by a Basic (the language) programmer (who learned on a C=64). In any event I persist as I know I will have "full employment" for quite a while.
The only saving grace is that there is some sort of version control, and we can always point a finger at the person who "broke it".
Life goes on.
