These utilities have been around long enough that their syntax and semantics have basically ossified long ago. A similar statement could be made of K&R C, which isn't an official standard, but one generally recognized in the C progamming community. (OTOH, there are POSIX standards for lex and yacc which are described in some detail in the O'Reilly _Lex & Yacc_ text.) > that either someone (Jeremy) would have to deal with the headache of > trying to maintain compatability between various lex and yacc > flavors, Given that CircleMUD is a unix app, that automatically eliminates the MS-DOG varieties of lex and yacc. This leaves the AT&T, Berkeley, POSIX, and GNU "variants"; and, these only signicantly differ by esoteric command line parameters and possible error diagnostics. The exceptions are that some versions have known, documented bugs; and, the GNU versions have unique extensions (which could be ignored for portability). Personally, I'd be more concerned with generic compatabilities between different flavors of _unix_ and not for lex and yacc. It's safe to say that there are many more significant differences between BSDish and SYSVish unixes than there are differences between the limited varieties of lex and yacc.
