Thanks. I was being lazy. I understand old Latin, Greek & Cyrillic scripts used only one case? And that modern Georgian does not distinguish cases though its alphabet has *several* variants. Osage is very new and Cherokee script was designed in early 1800s (influenced by the europeans). So it seems a) case sensitive scripts are mainly alphabets and b) lower case letters must've been a later addition. [I can see why case was never added to abugida languages like the Indian languages -- they already have a large number of glyphs and complex shapes to remember!] Getting back to programming languages, I am not sure case distinction really helps. Many of the earlier languages such as Algol, PL/I, APL, Pascal, Fortran, Cobol, Lisp didn't have it and I don't think it was solely due to an attempt to pack more chars in a word. Capitalization can improve legibility in written languages but the meaning of a word often doesn't change in spite of case change. In modern PLs the meaning can be entirely different, and even the category (DO vs do) and I am not sure that increases legibility. Not to mention the camelCaseHorror. Much prefer hyphenated-words (and use of space before the negative sign when needed).
