Quoting http://www.place.org/~nop/lua/ : lhf posted instructions for using the enhanced bin/lua from Lua 4.1-work in Lua 4.0. That bin/lua includes readline support, = as a shortcut for print, and automatic support for statements that span lines. I've created a patch against the standard 4.0 distribution that implements those changes, adds config support, and updates the documentation. http://www.place.org/~nop/lua/enhanced-lua.c.diff.gz Jay
