Global properties and functions
Properties: none. Functions: akey band, bnot, bor, bxor, lshift, rshift eval exit Keys mmode msgbox print prompt Notes: 1. Functions band, bnot, bor, bxor, lshift и rshift (bitwise operations) are global aliases of the same-named functions of bit64 library. (see LuaFAR manual). 2. Functions akey and mmode, when called from within function condition of a macro, return false. 3. For uniformity sake, all the above functions (except the bitwise ones) are duplicated in table mf, for example: eval и mf.eval reference the same function.
