If you'd be willing to open the discussion from "English usage", I can give you a couple of valid reasons for upper/lower case. It's rather difficult to look at a LIST and pick out the directorys, sometimes. My solution to this is that all DIRECTORIES are capitalized, while all Filenames are either lowercase or have only the first letter capitalized. Lets the directories leap right out when you do a LIST. In C, the standard procedure is to use all uppercase for MACROS and DEFINES, and lowercase for everything else. This makes it immediately obvious when you look at the code that PI and INDEX are constants, whereas picalc and indexptr are variables. Neither of these are required nor enforced, and they don't relate to your challenge, but I thought I'd mention a couple of valid uses I've found.
