LOOKING UP WORDS

Is your word a reserved word or a built in library?

Is it part of standard Lua? If not it may be part of RiscLua, so see the libraries riscos or lpeg.

Remember that unreserved names are not fixed to the extent that they may be in other languages. For example, if a library called foo contains a member called bar then the value foo.bar may appear simply as bar when the syntactic environment has been set to foo.
