Who is the world's oldest working programmer?

One is an arithmetic interpretation; the other a bitwise-logical interpretation. I figure that Paul would defend his "C works on everything" by saying that you can emulate boolean operations on emulated variables. But that's just hiding it all under the bushel of Turing-completeness. I can emulate a PDP-11 on a 1620 (or vice-versa), given enough memory and code. That ignores the best features of the architecture, such as variable word and record length. Recall that words are addressed by their highest (least significat digit) address (e.g. if you have a number that's 012345, it's the address of the '5' digit), but records, (i.e. the character string "HELLO WORLD" is addressed by the "H"). FORTRAN got around this by having no character nor pointer types and no boolean operators (at least in its basic FORTRAN II form). I'm not sure that C would know what to make of record- or group marks, or numeric blanks. --Chuck
